Long-term, regulations are either bypassed or dismantled, or the regulatory agencies are captured. Either lead to the same cyclical result where in the euphoria/bubble state of capitalism, existing regulations are removed to allow the system to grow faster/higher, and once the economy inevitably busts and (poor people's) lives are lost/ruined, then some regulations are added to "not let this happen again". At least, until the next boom cycle begins. We've already seen this play out and we're at the point where we can't see it play out again as that will literally lead to a human-led mass extinction event.

"Regulatory capture" is one way that regulated capitalism can fail. Bring that, I'm not sure.
