As a college student and young adult I had always envied his fame, his intelligence, his money (post-Reddit acquisition), and the strength of his convictions. And yet, in that moment in early 2013, he was dead, and I was working a good job at Google (and this was 2013 Google, when it was still a nice place to work doing things that I could generally approve of). And he'd died doing the stuff that I wanted to do but had been too chickenshit to actually carry out.
I think that this illustrates why the world is the way it is. All the true altruists are dead, killed for their altruism. It is adaptive, in a survival sense, to think of yourself and your own survival and not worry too much about other people. Ironically, this is what my therapist was trying to get me to realize.
But I think this also goes back to the GP's point. When people at wealth level x give to people at level x-1, it doesn't raise the people at x-1 up to x. It brings the person at x down to x-1. There are more people at x-1 than x, after all; you could give everything you had away and mathematically, it would lower your net worth significantly more than it would raise theirs. And of course, it doesn't do a damn thing about the people at x+1. Why can't they donate instead, where their wealth would do an order of magnitude more good?
There actually do exist people who are like that: they would rather spread their wealth around the people at wealth level x-1, joining them at that level, than raise themselves up to x+1. I've met some; most poor people are far more generous than rich people are. That is why they are poor. But then, it doesn't solve the problem of inequality, they just disappear into the masses of people at level x-1.
So thats essentially communism right? Is human nature incompatible with communism or is capitalism incompatible with human nature?
In the American golden age of capitalism from ~1950-1970, the top marginal tax rate was 90%, and so you didn't have CEOs get paid more than about 3x the median worker, because the government would get it all. Instead, they got perks. Private jets. Positions at the company for their kids. Debaucherous holiday parties. Casual sexual harassment of secretaries.
In Soviet communism, all production was centrally planned by government bureau run by party members. It was not uncommon for these bureaus to make mistakes, leading to severe shortages for the population. Nevertheless, these shortages never seemed to really hit the party members responsible for making the plans. Power has its perks.
And that's also why reforms attempting to reduce economic inequality need to focus on power rather than money. There have been a number of policies that do meaningfully raise standards of living for the poor: they're things like the 13th amendment to the (US) Constitution, the 1st amendment, the jury trial system, free markets, anti-monopoly statutes, bans on non-competes, etc. What they all have in common is that they preserve economic freedom and the power to make your own living against people who would seek to restrict that freedom and otherwise keep you in bondage.
