I know there are good regional banks who put deposits in relatively safe low-risk stocks such as utilities and the like, but they are the exception and not the rule.
Remember, if Glass-Steagall was still in place in 2008, when Lehman Brothers collapsed the effect on the economy would be like what happened in 1987: banks become the economic backstop to prevent an all-out financial crash. In 2008, without Glass-Steagall protections, we came very close to a 1929-style complete collapse of the entire banking system--it was only the financial success of Apple, Google and the biotech companies that finally began to get the US economy back on its feet by 2011.
Frankly...I’d be surprised if Hitlery knew what Glass-Steagall was without being prompted by one of her toadies. Which probably explains why the questioner was shown the door.
