That is how you become a serf. There are lots of mathematical and psychological reasons that the rich get richer. We live in a society with the economic freedom to enable this. You propose restricting economic mobility, so the rich don't get superrich. You also propose increasing the tax burden on the super rich, since there's a cut-off. The top 1% currently pay 45.7% of the taxes, so to drop wealth by a couple orders of magnitude you'd basically have to change that to 100%.

Thus, you have a feudal lord that pays for everything, and his serfs which don't have the economic freedom to break out of economic slavery. Joy, we get to return to the dark ages.

As for having 10,000 times the average wealth, ask your friends what their net worth is. Half of them are probably broke or in debt, so let's assume their worth to be $1. (Economic freedom means you can win OR lose.) If you have more than $10,000 I advise practicing what you preach and trade your car for a junker, sell your house, and anything over $10,000 in assets should be given to your friends.
