Free market fundamentalists
Even those guys agree that infrastructure requires tax and spend. That fraud needs to be regulated. That monopolies skew the market toward inefficiencies. And that negative externalities, (e.g., pollution) need to be regulated.
I'm way beyond that line of thinking. The way I see it, "inefficiencies" created by things like labor laws, safety regulations, and general social spending are a small price to pay for a society that meets human needs. And in fact many of these things actually strengthen the economy. Efficiency that creates unnecessary human suffering is socially destabilizing. A free market that causes Climate change but left to its own devices cannot solve it needs regulation.
