I'm not sure where your facts (or opinions) are from.

There is a coming wave of retirees, and an associated decrease in the workers per retiree to support them.

See page 12, page 15.

If you both are not understanding the issue, and not interested in learning about the details, then maybe you shouldn't take a strong opinion on the matter.

baby boomers are people born between 1945 and 1960. Meaning people between 63 and 78 yo. All of them are already retired, and the oldest ones are starting to die.

https://www.populationpyramid.net/france/2022/ doesn't look like it. The bulk of population just started going through the retirement age. Click -5 6 times, then start clicking +5 and watch how it moves.

the bump between 2017 and 2022 is mostly around the 75 yo slice. That's the beginning of baby boomer generation. Meaning this generation has been retired for more than 10 years now.

It's going to be 10 more rough years, until 2032, and then the shape stabilizes. Changing the age from 62 to 64 won't change anything to this generation impact on the system.

Now is the 2032 shape sustainable with the current retirement age ? that's another question, but it's not a matter of protecting against the baby boomer impact.
