Investing is risky work. Entrepreneur-type investing is the riskiest of all. Investors must evaluate the chance and amount of gain, as compared to the amount of risk and work involved. When taxes reduce the gain, and fiat gov't makes it more difficult to predict gain, investment drops Most wealthy folks don't really have to make the sort of risky investments that move a vibrant economy forward. Most mature folks have figured out it is much easier for a rich person to make money than a poor person. When the rich are breaking even, the poor are getting taken to the cleaners. When the rich are losing money, they just go someplace more friendly.
