It depends on the type of government and population you have. There's no perfect answer to that, it's mainly a philosophical one. Since I live in a social-democracy, I think money injection in certain parts of the society gives awesome results and it's important to have a strong government.

But I'm biased since, in my nation history, francophones were considered as the "white nigger" of America. Being second-class citizen, the free market was rigged against us and the anarcho-capitalism model made us poorer. It's when we decided to build a strong government aimed toward social-democracy that we evolved tremendously as a society.

I think free market is a fallacy honestly. In any free market, there's always a gang that becomes stronger than the rest and where they start to makes the rules. Either you follow them, either you're out. So, in a way, free market tends to create governments within themselves. If governments have to be created, I prefer having the choice of voting for it.
