I think you also have to organize and get money out of and honest people into politics. Just consider Stav Shaffir, who near the end of this video makes some very good points about idealists and their aversion to power:

If more people were "more like that", and if more of them would manage the "quantum leap" into serious politics, that would still be slow and painful, but at least more than asking for things or offering facts. Don't get me wrong, that is all very necessary and good, but it's not quite enough IMHO.
