The best thing is to read a lot of sources yourself and try and make up your own mind. Everyone's trying to sell something, whether it's the libertopians telling you that if there were just no regulations at all, everything would finally work out, or the complete-faith-in-the-government left which thinks that everything will be just great once we regulate everything down to the last detail (caricatures... well, yeah, sorry guys, but reams have been written on this stuff, and I kind of like satirizing it).

Also, the above fundamental philosophical differences are one reason why this stuff just shouldn't be here: people completely disagree and are just going to go on and on and on without really concluding anything.
