Not in France they aren’t. And not in most EU countries that still rely in pay as you go pension systems.
For comparison. France’s pension funds (total public and private) are 12% of their GDP. Total EU pension funds are also around 20% of total EU GDP. USA pension funds are 170% of their GDP!!!
Yes, we have a pays-as-you-go pension system in Denmark (sigh). But regulations were also changed a while back such that employees must pay into a pension scheme of their own.
In our case, that's handled via your employer and there's a minimum contribution limit and often incentives to pay a higher level.
