Public pensions do rely on current contributions. But Ponzi schemes trick investors by financing initial returns out of investments. Not at all the same thing
Is there any truth to this? Or is he just being hyperbolic?
Worked well when the country was growing in population, not so much now that the growth is negative (especially working population). Hence it's the primary reason why we renamed our "Oil fund" to "The pension fund"[1].
For private companies it's different, they have to actually put money in a personal pension account for each employee. The company can't fool around with it afterwards.

While there's a rule in place to withdraw less than 3% of the value to ensure long-term survival of the fund, due to its size that now constitutes a significant part of the national budget. For 2026 they'll be withdrawing 2.9%, which translates to about 580B NOK, or $58B USD.
However the total spending in the 2026 national budget is 2200B NOK, or $220B USD. So the fund covers about 26% of the budget for 2026.
Lets just say it would be very painful if we suddenly did not have that fund.
If they liquidated it today and put it all in a bank account and wanted to spend it all inside the country, they could fund over 10 years worth of 2026 national budgets in its entirety.
Why don't you just invest yourself?
Well first because pensions being large scale investors can get better results and second because most people don't do the smart thing and put some money aside for a rainy day, a pension forces that.
In such a scenario the incoming people function more as a failsafe, the investment should handle paying out for your pension but in cases where there have been a problem in the market, you have outlived your pension expectations etc. you then end up having the failsafe of new people always putting money in. Thus giving the pension an extra layer of security than just investing for yourself.
on edit: of course there can be difference between governmental and company pensions.
These pensions that invest and compound your investment over time can turn a comfortable middle class life into a very comfortable retirement, the American model instead of the European model of these kinds of company investments tends to be more risky however, and so there can often be scandals where you were supposed to be getting a pension but the rich company looted you and you're screwed hah hah.
For example you may get a pension of 5% of your wage goes into the fund, and the company you work for matching that, indicating 5% extra wage that is not part of your taxed income. Depending on how your life is structured it may be smarter to go for a pension.
