It's essentially a problem of corruption. If you want to 'beat the system from within', for instance by joining the political stage or by becoming insanely wealthy through some corporate scheme so you can use your power to lobby you will end up being such an integrated part of the system that arguing against it will argue to a large extent against your own interest. That's why the situation persists. If you could convince large numbers of voters to vote their own interests instead of being tricked into voting based on inconsequential talking points you'd end up with Ralph Nader for president instead of a democrat or a republican. Fix that and you can fix everything else with relative ease. But that's a very hard problem to fix, if it is even possible. So you get individual fighting windmills at a level that they can relate to instead.
