Ignore the shit heads, the question that you should be really asking is are politicians as a whole so corrupt and the system employed to get them there so corrupt that it dose not matter what the age of the voter is as it has no consequence to those who are in power.
First off, the belief that we have a fair and just system of politics is just that, its a belief, abit like religion, where people just believe in an idea but not requesting any proofs of validity of same. No, all politics and politicans whomever they may be in whatever country in whatever time are corrupt and bought off by the parasite.
Its just an illusion, nothing more, the best thing people could do right now is to not vote at all in any nation that has the right to vote. Because that would bring the system down and that would facilitate change, hopefully for the better.
