I really don't understand this reform. However for me to understand it, one would need an 8 hour video stream full of spreadsheet with an actual expert working on that reform.
And no media is ready to do that
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.
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.
