Oh well we can always go back to stashing fiat and watching our stash erode away through inflation and microscopic interest rates.
Whatever you do have fun along the way.

Or you can invest in the stock market and make reliable long-term returns.
Or real estate.
Or gold.
Or fine artwork.
Or bonds.
Or all of the above.
I know you were probably being facetious - but as the Fed normalises interest rates, some investors will stop looking for exotic investments and go back to safe boring bonds. The suppressed interest rates created an appetite for risky investments because people didn't have much choice - but that era is ending. I expect the stock market to crash as well, as people rotate out of it and back into safer investments that yield an interest.
