Not sure where you are getting your figures, but let's imagine a simple scenario. Hillary and Bill Clinton go out and do various speaking engagements. The payments for these "services" are paid to Clinton Shell Foundation Inc., of which Hillary owns 60% of the shares, and Bill owns 40%. They pay the corporate rate for that income, which will now be 20%, instead of personal income tax rates (even under past tax schemes, they would pay less than the personal rate). Add to that the fact that there have always many more deductions, write-offs, etc. for a business, further lowering the taxable amount. Want a private jet? Bought and paid for by the corporation. Lodging at a ski resort in Davos? Corporation pays.
