I don't think the average American wants politicians this old, they are being chosen by their political parties as having the highest chance of winning because we have a broken voting system that encourages fewer candidates per party so that they don't steal votes from each other.
That is why we need ranked choice voting, so that more candidates can run without competing and we could vote for people we actually like instead of voting against candidates we don't like.
Not to mention the need to level the playing field in terms of campaign financing which currently makes it more likely for more established politicians to have collected funding from private organizations, superpacs, and corporate lobbying.
This means that the politicians who are in the pockets of the capitalist elites are more likely to win and to enact the will of these corporations.
Capitalism is the driving force of almost everything that's wrong in America. [1]
I agree that bailing out a corporation is not very capitalist, but that is not the primary goal of corporate lobbying. I believe it is mostly about keeping their industry legal, unregulated, low-taxed, etc.
