When a former US President makes $40million since leaving office, why do taxpayers still subsidize him?

I agree completely. The first Bush & Clinton made $200,000 a year, & W is making $400,000 a year. Then throw in book deals, lectures, & apperances where they can make $50,000 & up. It's ludacrious that we are still paying them for something they used to do. If I could get a percentage of my salary from the jobs I've had in the past I'd be set, to bad it doesn't work that way for normal people, maybe I should run for President. Ya maybe ???
