The goal of a succession of French legislative pension reforms over the last 25 years was to absorb mounting present and future pension deficits. However, relentless demographic change continues to increase the imbalance between pensioners and contributors.
The French government is also steadily juggling the three variables on hand: contributions, pensions, and retirement age. Pushing back retirement age is, to say the least, unpopular. It is perhaps to avoid meeting the issue head-on that incentive measures were put in place to make retirement age totally random, even unpredictable.
