What exactly are we talking here? Practical goverment? Theoretical government?
Theoretically, I like the philosopher king, as long as he's the omniscient, benevolent, omnipotent, disinterested ruler he's outlined to be. Of course, that's impossible. And it sounds like religious utopia to a hilarious degree. Communism is similar, except it leaves out omniscient, omnipotent, and practical application fails at steps benevolent and disinterested, so no thanks.
Practically, Social Democracy. A Democracy with a regulated market and a social safety net.
