I wish we would stop talking about "left" or "right" politics. Neither are well-defined or rational. It leads to gross over-simplification of important issues by tempting people to dismiss policy X as "socialist" or "fascist" without logically looking at the facts.

Let's the example of financial market regulation you allude to. The reason why it could be a good idea is that a truly free market tends to undervalue risk. For example, if I bought a car from you and it was an optimal deal for both of us, neither of us considered the cost the rest of the population would incur in congestion, pollution, etc. That is considered systemic risk and because it is undervalued it tends to build up. My understanding here isn't full, but I assume those are the forces behind bubbles. Regardless, market regulation is a tool to address these concerns, not a political device to drive the US to socialism.

One of the reasons why I enjoy such articles is that they encourage critical thinking about what is so often mistakenly handled exclusively in the political arena.
