The wealthy are better placed and motivated to run! Plus it's in their DNA, as it were - self-promoters, narcissists! And when they get there they are going to accomodate those they favor -- the people who share their interests and thus helped them get rich and onto win power in the first place! That said, if the system falls, the corruption will be even greater from the so-called emancipators of that [current] system -- The internet allows instant political gratification, hence the current state of affairs -- but as Plato would attest - better to fix what is a good idea [current democracy] than let demagogue [Hitler, Trump, Jinping] takeover as mistakingly categorized Gods!
