Assuming that the money is all used for altruistic purpose, I could agree with your point. But we know that this money is often used for not so altruistic purposes like investing in PE which asset strip the productive parts of economy or use the money to influence politics and elected representatives via lobbying.
In most advanced economies today, that's equity. The ordinary person thinks of wealth as money lying around in the bank, which the rich person refuses to spend on anything useful. And instead either hoards, or spends on luxury things which cause resentment to the remainder.
The real question is for most people today its easier than ever to invest and then give it to their children. Why aren't people doing it?
The median person in the US has about $8k, which is basically enough to cover one emergency.
I've been out of full time work for 2.5 years now and had to slowly dwindle my 401k when emergencies popped up.
I didn't think this community was this isolated from the economy given the hundreds of thousands of tech workers displaced these past few years alone. Take a look at what it's like for non-tech workers and come back to ask that question.
Yup, altruistic job nakers, huh?
