People will have to vote for non-captured candidates (good luck finding them) or protest in large enough numbers that the system will change. Those people will also have to be critical thinkers to a degree that they can consciously push back against the wall of marketing and propaganda pumped out by those in power with money. And they will have to self educate since governments generally don't teach people these skills while they have them in school for 12 or more years. From my point of view the future looks pretty grim but I'm certainly hoping to be surprised or corrected!
