Note that the recent presidential election was in large part decided by which groups didn't vote. The viewpoint that politicians are all the same, voting doesn't matter etc. is a also a political opinions which benefits certain interests.
I'd like to see less money in politics, either public funding or donations restricted to small individual donors, and I personally think a good candidate for higher office should have worked at least one shit job in their life. But the other extreme is equally absurd.
The President is literally the chief executive of an organization of millions of people. While some good old fashioned down-to-earth-ness is great for knowing what to do, if a Presidential candidate can't manage a large organization efficiently, pick competent subordinates and delegate authority effectively, they ain't never gonna get anything done as President.
The President is like the one race where a two year PR stint managing a few thousand people spread across all fifty states and a few territories is a good interview for the job.
