When billionaires like Warren Buffet tell Jesse Eisinger that he doesn't pay tax because "he thinks his money is better spent on charitable works rather than contributing to an insignificant reduction of the deficit," he is, at best, technically wrong about why we tax, and at worst, he's telling a self-serving lie. The US government doesn't need to eliminate its debt. Doing so would be catastrophic. "Retiring the US debt" is the same thing as "retiring the US dollar."

So if the USG isn't taxing to retire its debts, why does it tax? Because when the USG – or any other currency issuer – creates a token, that token is, on its face, useless. If I offered to sell you some "Corycoins," you would quite rightly say that Corycoins have no value and thus you don't need any of them.

For a token to be liquid – for it to be redeemable for valuable things, like labor, goods and services – there needs to be something that someone desires that can be purchased with that token. Remember when Disney issued "Disney dollars" that you could only spend at Disney theme parks? They traded more or less at face value, even outside of Disney parks, because everyone knew someone who was planning a Disney vacation and could make use of those Disney tokens.

But if you go down to a local carny and play skeeball and win a fistful of tickets, you'll find it hard to trade those with anyone outside of the skeeball counter, especially once you leave the carny. There's two reasons for this:

1) The things you can get at the skeeball counter are pretty crappy so most people don't desire them; and ' 2) Most people aren't planning on visiting the carny, so there's no way for them to redeem the skeeball tickets even if they want the stuff behind the counter (this is also why it's hard to sell your Iranian rials if you bring them back to the US – there's not much you can buy in Iran, and even someone you wanted to buy something there, it's really hard for US citizens to get to Iran).

But when a sovereign currency issuer – one with the power of the law behind it – demands a tax denominated in its own currency, they create demand for that token. Everyone desires USD because almost everyone in the USA has to pay taxes in USD to the government every year, or they will go to prison. That fact is why there is such a liquid market for USD. Far more people want USD to pay their taxes than will ever want Disney dollars to spend on Dole Whips, and even if you are hoping to buy a Dole Whip in Fantasyland, that desire is far less important to you than your desire not to go to prison for dodging your taxes.

Even if you're not paying taxes, you know someone who is. The underlying liquidity of the USD is inextricably tied to taxation, and that's the first reason we tax. By issuing a token – the USD – and then laying on a tax that can only be paid in that token (you cannot pay federal income tax in anything except USD – not crypto, not euros, not rials – only USD), the US government creates demand for that token.

And because the US government is the only source of dollars, the US government can purchase anything that is within its sovereign territory. Anything denominated in US dollars is available to the US government: the labor of every US-residing person, the land and resources in US territory, and the goods produced within the US borders. The US doesn't need to tax us to buy these things (remember, it makes new money by typing numbers into a spreadsheet at the Federal Reserve). But it does tax us, and if the taxes it levies don't equal the spending it's making, it also sells us T-bills to make up the shortfall.

So the US government kinda acts like classical physics is true, that is, like it is a household and thus a currency user, and not a currency issuer. If it spends more than it taxes, it "borrows" (issues T-bills) to make up the difference. Why does it do this? To fight inflation.

The US government has no monetary constraints, it can make as many dollars as it cares to (by typing numbers into a spreadsheet). But the US government is fiscally constrained, because it can only buy things that are denominated in US dollars (this is why it's such a big deal that global oil is priced in USD – it means the US government can buy oil from anywhere, not only the USA, just by typing numbers into a spreadsheet).

The supply of dollars is infinite, but the supply of labor and goods denominated in US dollars is finite, and, what's more, the people inside the USA expect to use that labor and goods for their own needs. If the US government issues so many dollars that it can outbid every private construction company for the labor of electricians, bricklayers, crane drivers, etc, and puts them all to work building federal buildings, there will be no private construction.

Indeed, every time the US government bids against the private sector for anything – labor, resources, land, finished goods – the price of that thing goes up. That's one way to get inflation (and it's why inflation hawks are so horny for slashing government spending – to get government bidders out of the auction for goods, services and labor).

But while the supply of goods for sale in US dollars is finite, it's not fixed. If the US government takes away some of the private sector's productive capacity in order to build interstates, train skilled professionals, treat sick people so they can go to work (or at least not burden their working-age relations), etc, then the supply of goods and services denominated in USD goes up, and that makes more fiscal space, meaning the government and the private sector can both consume more of those goods and services and still not bid against one another, thus creating no inflationary pressure.

Thus, taxes create liquidity for US dollars, but they do something else that's really important: they reduce the spending power of the private sector. If the US only ever spent money into existence and never taxed it out of existence, that would create incredible inflation, because the supply of dollars would go up and up and up, while the supply of goods and services you could buy with dollars would grow much more slowly, because the US government wouldn't have the looming threat of taxes with which to coerce us into doing the work to build highways, care for the sick, or teach people how to be doctors, engineers, etc.

Taxes coercively reduce the purchasing power of the private sector (they're a stick). T-bills do the same thing, but voluntarily (they the carrot).

A T-bill is a bargain offered by the US government: "Voluntarily park your money instead of spending it. That will create fiscal space for us to buy things without bidding against you, because it removes your money from circulation temporarily. That means we, the US government, can buy more stuff and use it to increase the amount of goods and services you can buy with your money when the bond matures, while keeping the supply of dollars and the supply of dollar-denominated stuff in rough equilibrium."

So a bond isn't a debt – it's more like a savings account. When you move money from your checking to your savings, you reduce its liquidity, meaning the bank can treat it as a reserve without worrying quite so much about you spending it. In exchange, the bank gives you some interest, as a carrot.

I know, I know, this is a big-ass wall of text. Congrats if you made it this far! But here's the upshot. We should tax billionaires, because it will reduce their economic power and thus their political power.

But we absolutely don't need to tax billionaires to have nice things. For example: the US government could hire every single unemployed person without creating inflationary pressure on wages, because inflation only happens when the US government tries to buy something that the private sector is also trying to buy, bidding up the price. To be "unemployed" is to have labor that the private sector isn't trying to buy. They're synonyms. By definition, the feds could put every unemployed person to work (say, training one another to be teachers, construction workers, etc – and then going out and taking care of the sick, addressing the housing crisis, etc etc) without buying any labor that the private sector is also trying to buy.

What's even more true than this is that our taxes are not going to reduce the national debt. That guest you had who said, "Even if we tax billionaires, we will never pay off the national debt,"" was 100% right, because the national debt equals all the money in circulation.

Which is why that guest was also very, very wrong when she said, "We will have to tax normal people too in order to pay off the debt." We don't have to pay off the debt. We shouldn't pay off the debt. We can't pay off the debt. Paying off the debt is another way of saying "eliminating the dollar."

Taxation isn't a way for the government to pay for things. Taxation is a way to create demand for US dollars, to convince people to sell goods and services to the US government, and to constrain private sector spending, which creates fiscal space for the US government to buy goods and services without bidding up their prices.

And in a "classical physics" sense, all of the preceding is kinda a way of saying, "Taxes pay for government spending." As a rough approximation, you can think of taxes like this and generally not get into trouble.

But when you start to make policy – when you contemplate when, whether, and how much to tax billionaires – you leave behind the crude, high-level approximation and descend into the nitty-gritty world of things as they are, and you need to jettison the convenience of the easy-to-grasp approximation.
