I work in finance and the number of widows/divorcées (and widowers/divorcés, but notably fewer of those) I have talked to who have no income of their own, no savings of their own, no accounts of their own, and no idea what to do with the money they have received from their spouse is frankly terrifying.
One woman told me openly, "Oh, I married at 21. I went right from Daddy to Hubby, I never had to pay my own bills. Now I'm lost. This is all so confusing to me." She was 43 - not old, not senile, just incredibly sheltered and now thrust into the world with little or no support system and an overwhelming learning curve.
Even if you get money in a divorce, the skills that come with earning, managing, and spending your money are vital. People who don't have those skills, or have let them atrophy from years or decades of disuse while society and technology kept moving, are in a profoundly precarious and vulnerable place.
