$500K is at the top end of the gently sloping line that comprises 99.4% of all incomes. While quite large, it's part of that normal progression. People half a percentage point below don't make a helluva lot less, but people half a point above make 4X as much, and the curve goes near vertical from there. People whose incomes fall consistently in that part of the curve are truly wealthy, and their income is derived largely from investment. Alkemyst just looks rich, because he has many of the visible trappings of people much better off than he is. OTOH, living large means he's just as vulnerable to the changing fortunes of employment as people making a lot less, because his income is not based on investment.
Which is where truly wealthy people have it made over the rest of us, because their net worth is enormous. A 5% return on $1M nets $50K/yr. Alkemyst would need $10M actively invested to obtain his present income from investment. People at the entry level to the top .1% would need $40M to make the $2M/yr putting them at that income level. Obviously, they'd pay a lower tax rate on capital gains & dividends than Alkemyst, who works for his money. They don't spend nearly all of what they make, either, but reinvest much of it. In a really, really bad year, they might have to liquidate some small part of the principal to maintain their lifestyles, which they'll more than make up for in good years.
They can't be financially drowned in the down side of a business cycle, at all. It's actually just a different kind of opportunity to make money. Sometimes staying on top is a simple as holding other people down.
