You don't think the guy that buys the factory that a thousand people work in contributed more? He should get $10/hour for laying out a couple billion?
When I have $1bn and I spend $5 million x 100 risky investments, then losing $500 million means that I, my children, grandchildren, great-grandchildren will still be richer than the top 10% in even the most developed country.
At some point the whole risk-reward shtick breaks down.
