Check out Uber/Lyft/AirBnB. All of them ignored regulations for long enough that the regulations eventually got removed.

I'm not aware of many regulations that were tightened in the past 5 years. Changed sure, but usually aiming for fixing regulations that no longer properly applied.

The regulations that "tightened" would be: FOSTA/SESTA

It's possible I missed a lot, but please enlighten me.

There's an article with examples here: https://en.wikipedia.org/wiki/Deregulation#United_States It doesn't seem like a comprehensive list. For example, I scanned the page for "Fairness Doctrine" and found nothing.

The hobbling of Dodd-Frank by Obama and its gutting by Trump, in each case at the behest of Wall Street, is an obvious example.

Cf. https://en.wikipedia.org/wiki/Glass%E2%80%93Steagall_in_post...

Your linked source does not support the claim, but rather talks about efforts to restore Glass-Steagall in some form and their failure, which is not a loosening of regulations, but a continuation of the status quo. I do acknowledge that the repeal of Glass-Steagall itself was a loosening of regulation, but that was 25 years ago.

The link was 'Cf', meaning it gives background on the part of financial regulation I talk about, rather than being a direct source. It talks about the rationale for not adopting Glass-Steagall-strength measures during the Obama years. During the Trump years, most US banks were exempted from Dodd-Frank in 2018 via the Economic Growth, Regulatory Relief and Consumer Protection Act.

Anyone in finance would tell you that Dodd Frank drastically changed how banks are run. Glass–Steagall was never reinstated because it had very little to do with the financial crisis. Many of the bigger players of the mortgage crisis never did anything related to commercial banking (e.g. Lehman Brothers, AIG).

Dodd Frank was not gutted by Trump. They lifted the asset cap so that the onerous regulatory requirements only applied to banks with $250B+ in assets, rather than banks with $50B+ in assets, as it was previously.

This was a great thing for consumers and banking competition. There is no reason a small bank with $50B in assets should have the same regulatory requirements as JP Morgan.
