This is not at all clear.

> Separating banking, investment banking, and insurance into separate legal entities and preventing the banks from consolidating into mega-banks prevented another a Great Depression for ~70years. Then roughly 8yrs after we repealed all that, we unsurprisingly had another Great Depression level financial crisis.

Are we forgetting the inflationary period in the 70s? How the gold standard was lost during this time? All the emerging market crises? How the USD has lost 98% of its value since the 70s? How inequality is sky high due to interest rate suppression causing asset price inflation? How we have a massive trade defect leading to an extremely large negative net-foreign-investment balance? Does it makes sense to you that countries that are much "poorer" than us are lending us money?

> The Fed’s lending support, along with govt stimulus, prevented the actual depression from happening, so you could argue that the Central Bank does have some impact on banking system stability. But it was only necessary because we removed the structural regulation that had maintained a stable banking system for over half a century.

We trade depression for inflation then. Is this good? Bad? Not sure. We are living in that experiment though. One day this excessive debt and money printing will catch up with us. It has happened to every single fiat currency in history.
