They don't. I'd like to see if there was some way of motivating more talented people to run for these offices. As it stands now, we tend to get power hungry people with limited abilities and little real world experience.
To get there, these politicians have to endure a level of public scrutiny not imagined by the fathers.
It would be nice to have better candidates with real world experience running for office. But even those few people with success in other areas who may want to serve charitably in government have to expose themselves to the nastiest set of conditions to do so.
I don't know what the incentives might be for folks like that but I doubt it's going to be money. So I don't see this move by Obama as being anything productive except to his pocketbook.
America's most successful businessman is running right now, and getting nothing but crap from people in his own party.
The "political class" does NOT want non-politicians running for office.
