“At the historical dawn of capitalist production,—and every capitalist upstart has personally to go through this historical stage—avarice, and desire to get rich, are the ruling passions. But the progress of capitalist production not only creates a world of delights; it lays open, in speculation and the credit system, a thousand sources of sudden enrichment. When a certain stage of development has been reached, a conventional degree of prodigality, which is also an exhibition of wealth, and consequently a source of credit, becomes a business necessity to the “unfortunate” capitalist. Luxury enters into capital’s expenses of representation. Moreover, the capitalist gets rich, not like the miser, in proportion to his personal labour and restricted consumption, but at the same rate as he squeezes out the labour-power of others, and enforces on the labourer abstinence from all life’s enjoyments. Although, therefore, the prodigality of the capitalist never possesses the bona fide character of the open-handed feudal lord’s prodigality, but, on the contrary, has always lurking behind it the most sordid avarice and the most anxious calculation, yet his expenditure grows with his accumulation, without the one necessarily restricting the other. But along with this growth, there is at the same time developed in his breast, a Faustian conflict between the passion for accumulation, and the desire for enjoyment.”
—Karl Marx, “Conversion of Surplus-Value into Capital,” Capital, vol. 1 (1867)
