I can’t help disagreeing with a lot of that.

it would be better if politicians were less removed from those they purport to represent, and as unbelievable as it may sound, Trump’s election is a step in that direction

I tend to want to stop talking about Trump vs Clinton, because they were both very poor choices — and I’m even going to go out on a limb and say Sanders wasn’t a great choice either, though I prefer him over Clinton (and at least I’m sure his heart is in the right place — I’m not sure that’s true of Clinton and I’m sure it’s not true of Trump). Our political process filters out the best people; I’ve heard anecdotes many times of people who don’t want to go into politics for reasons like “I don’t want to wallow in the muck.”

As I’ve written elsewhere, I don’t think Trump is actually going to do anything about corruption (which, to me, essentially just means government that, as you implied, no longer represents the people as it was meant to). Possibly just because he doesn’t know how. Trump’s hundred-day plan does have some anti-corruption elements:

FIRST, propose a Constitutional Amendment to impose term limits on all members of Congress;
FOURTH, a 5 year-ban on White House and Congressional officials becoming lobbyists after they leave government service;
FIFTH, a lifetime ban on White House officials lobbying on behalf of a foreign government;
SIXTH, a complete ban on foreign lobbyists raising money for American elections.

But there’s no campaign finance reform, no electoral reform, nothing about gerrymandering, and since U.S. corruption is home-grown, the last two promises are not likely to make a difference (and note that foreigners already can’t give money to U.S. campaigns). The first two are a good start; however, constitutional amendments are extremely hard to pass, and the 5-year rule would still allow lobbyists to be appointed to important positions, and still allow congressional officials to be paid handsomely when they leave office (maybe as “executives”, “consultants” or “public speakers” rather than as “lobbyists”). Thus, the effect of these policies will be minimal.

I always like to recommend people watch Lawrence Lessig, who wrote two books about corruption, explain the situation in brief; he also talks about Trump and corruption here.
