In the U.S. voting is for the elite only. The original constitution called for white free men owning land to be the only voters.
Naturally we have loosened that up a bit, but hell, do you really want *everybody* voting?
Seriously though if you can't be bothered to figure out how to register its probably a good thing you can't vote either. The idea that you have to actually take the time, go register, think about it a little bit might not be a bad thing. All kidding aside the constitution framers were terrified of an ignorant population voting on emotion.
