The problem is the majority of people who a drastic change in society would benefit lack the time, intelligence money, and effort it would take to make it happen.

Also societies are to big and segregated. Most people don't even know their neighbours and it would take a large combined effort to make a difference. Political parties and the media keep us all bogged down with less important problems which focus our attention in the wrong places. Ideological changes will never happen as too much is required of the masses than can reasonably be expected to actually take place.

So as an individual you can either get on with playing the game and make choices that optimize your short term life or spend your whole life trying to explain to disinterested folk why the game is fucking them and end up with nothing yourself.
