You should re-read Adam Smith's Wealth of Nations. Smith argues there is one class of entities we should trust less than government: rent-seeker businesses. It is imperative for the government to protect against their monopolistic tendencies, and those tendencies have never been stronger than they are today. Who opposes Net Neutrality? Only rent-seeker ISP's. Who's against environmental regulations? Again, rent-seekers. They complain about regulations making them uncompetitive when in reality, it is their poor business decisions. 

If you're feeling up to it, I also recommend all of Kenneth Arrow's work, which provides the mathematical underpinnings of the invisible hand. He proved the free market provides the most efficient welfare allocation, but spent the rest of his career showing there was no feasible way the free market can provide healthcare - only the government can do so in a fair, efficient way.
