What you are describing is essentially lobbying
Of course the board wants Clinton to open doors. That is why they pay him.
But the thing you apparently can't grasp is that there is a whole class of people who command enormous speaking fees, in and out of the government. The fees of the Clintons were not out-of-the-ordinary for A-listers. It is obscene, but it is not unusual, and not indicative of corruption.
I look forward to posting this twelve more times, at least.
