Look at the filings for big companies. Usually the top incomes and options are given to the CEO, COO and CFO. CFOs are often sitting on large sacks of money and directly participating in the finance industry. Even companies with no other ties to finance or banking are usually playing around with the same mechanisms as hedge funds, banks and other investment organisations. You are making the mistake of thinking the only income a business makes today is from its core products and services. Most large businesses are making plenty of income from interest and investments if they aren't overflowing with debt.
