While I am distressed at the possibility of removing all these impediments to financial doom, carefully built brick by brick out of the ashes of former conflagrations, I think it’s important to note that none of these sorts of financial disasters happen overnight. (Wars, pandemics, and SVBs excepted, of course.)
It took years after George W Bush charged in on his deregulation steed before the housing market imploded. Six years went by, during which his advisors steered away any regulatory attempts to rein in the financial sector, aided by the Libertarian minded Alan Greenspan.
The 1929 crash happened in October, but it didn’t start with Hoover’s inauguration in March. The kinds of stock excesses and margin betting were prevalent during the prior administration(s) and only came to fruition years later. Likewise the S&L banking fiasco at the end of Reagan’s term, for which he paid no price at all.
We are lucky that the 2008 crash happened when Bush was still in office, because it pinned the blame almost perfectly where it needed to be. (Almost, because Clinton was complicit in some of the deregulation, too.)
There’s nothing that says this recent round of “forget all those lessons we learned” will cause an explosion within weeks or months. It takes a long time for the system to get out of whack, for players to figure out the dark corners to run their grifts, and for enough detritus to pile up to actually threaten a large financial system such as we have. That doesn’t mean it won’t happen - just that it will take time. (Indeed, at first everything will look peachy! Remember 2006’s “Everybody Gets A House”, and the good times under Coolidge.)
Of course I’m one who moves in and out, eschewing the conventional wisdom of never doing anything, so my view is different. I’m not a fan of the wanton destruction, I just don’t suffer it as some do, chanting “Why worry? I can never happen to me.”
