It should be virtually impossible to gain more than 100 million dollars.

If you have 100 million invested, then you're getting like $500,000 a month just in growth from either appreciation or interest, depending on the investment. Who needs that? For what? there's something terribly wrong with purple who have that much wealth and are even consider needing more wealth. All wealth is consolidating. Our world is already so anti-entrepreneurship already, and everything is pushing companies towards monopolies. These billionaires with their monopolies are doing everything they can (including buying your politicians) to continue accruing more wealth. 100 million dollars is enough for 70 people to live in the mid west on a decent salary perpetually. Salaries over 10 million a year should be treated the same since that will easily become 100 million in wealth in a decade.

There are about 3000 billionaires worldwide and about 1000 in the states. There's probably about 30,000 people with over 100 million dollars. These people are deciding how our world works.
