why is that? why couldn't the private approach (withholding x amount per paycheck, adding to a pension fund) work at scale?

People are living longer after retirement (over 10 years longer since the 1970s) and birth rates have fallen. Expenditure surpasses income eventually. There are other factors but that seems to be the main issue.

Making the pension a public problem won't fix it. The money has to come from somewhere.
