I believe in government because I elect its representatives.
I didn't want to hi-jack the Crypto thread so I'll start the discussuion here.
Although you get to vote for the candidate of your choice, the candidate is chosen by the elite. (The guys with the gold)
Democracy as we know it is bought and paid for. To get elected you have to campaign. To campaign you need money. The guys with the money decide who gets to be nominated. The guy who is nominated promises to give you stuff for free that he pays for with your money. When a decision has to be made, who do you think the guy you elected will listen to, the guy who elected him of the guy who financed him?
Not saying the democracy isn't the best system, only saying that if your vote really made a differece, they would probably find a way to make it illegal.
