As Ajay Shah points out, we don’t just regulate our financial system, we micro-manage it. When things are going well in the US, and we make the case for deregulation, we get the answer: “See, even in the US, we don’t have a completely free market system. Even they have regulations. How can you propose that we junk ours?”
When things go wrong in the US, we get the answer: “See what happened to the US because they followed a free market system? How can you propose that we junk our regulations? We need more.”
This bias ensures that we will always follow suit when the US moves left, never when it moves to the right.
