Inequality has one obvious and intuitive effect: the decreasing marginal utility of money causes a decrease in total wellbeing with ncreasing inequality. In easier terms: a wealthy CEO gets less use out of the $1000 they spend on a bottle of champagne than a poor person would get from spending the same money on food for the family. This is basically a truism as long as people do any meaningful prioritization (which they obviously do). There is a countering effect where inequality is a needed byproduct to incentivize people to, for example, start businesses. This is also obviously true in general. The question is where these two curves intersect, I. e. whee the benefits are no longer enough to compensate the loss from unequal distribution. It seems likely that the US is long past this point at least in gerade to the compensation of lawyers, top executives, or stock traders. After all, these professions also exist in more equal societies and there’s no reason to believe people cut out to be high-charging CEOs in those countries choose to become couch potatoes and leave the $15,000,000 job to lesser individuals because they require $150,000,000 to even bother. On the startup side it’s a little more murky. But keep in mind that almost all startup founders come from the financial security of an upper-middle class family, and even in the US, the success of a Silicon Valley is rather unique. It may be easier attributed to network effects, excellent universities, the status of the English language, or the availability of capital. Wikipedia has this summery with some empirical evidence: Effects of inequality researchers have found include higher rates of health and social problems, and lower rates of social goods,[112] a lower level of economic utility in society from resources devoted on high-end consumption,[113] and even a lower level of economic growth when human capital is neglected for high-end consumption.[114] For the top 21 industrialised countries, counting each person equally, life expectancy is lower in more unequal countries (r = -.907).[115] A similar relationship exists among US states (r = -.620).[116] 2013 Economics Nobel prize winner Robert J. Shiller said that rising inequality in the United States and elsewhere is the most important problem.[117] Increasing inequality harms economic growth.[118] The economic stratification of society into "elites" and "masses" played a central role in the collapse of other advanced civilizations such as the Roman, Han and Gupta empires.[119] https://en.wikipedia.org/wiki/Economic_inequality#Effects https://en.wikipedia.org/wiki/Economic_inequality#Effects
