No disrespect, but why don't we just hope that the world will turn into Candyland and we'll all dance together in the gumdrop fields.
You can hold individuals accountable for their actions, but you cannot hold huge masses responsible. Our turnout is lower than other nations, and this is a product of our system, including our culture and government. We can't say "just go vote" when people know that they have absolutely no influence in what's gonna happen. You live in a district that's 90% republican and 5% independent, is there a point in voting in house election? No, and that's a systemic problem, that we set people up that, just by their not terrible standing with one particular group, it becomes practically impossible to hold them accountable for anything.
Now I don't think low voter turnout is in and of itself the problem. Milton Friedman said something in an interview (it's about the defecit, but the idea's the same). Never mind, couldn't find my copy. Anywho, the idea is this, a defecit is not in and of itself a problem, but it depends on the source of the defecit. If a defecit is primarily because of decreased taxes, that does not hurt the nation, but if the defecit is because of increased spending, it is. The same idea goes here. If voter turnout is low because the people who have not studied thoroughly enough to make informed, intelligent decisions, that's not a bad thing. Now if instead it's because large amounts of people have realized that, due to features of the system, voting is futile, that's a ****in problem.
