Most politicians, and pretty much all viable ones who have any chance of getting elected or can control the direction of any major party, are either rich bastards themselves or cronies and sycophants to the rich, the fact that they're the only choices we get to vote for doesn't make them "representative" it just means they've completely stacked the deck so that we have no choice but to vote against ourselves no matter who we vote for. Democracy itself hasn't totally failed us (yet, I hope) but our political system of representation and the current institution of democracy certainly has.
