Well that's pretty crazy - "we screwed up, so now you have to pay us to rectify our mistake".
Seems like an enormous political liability.
Here in the US, Social Security is sometimes referred to as the "3rd rail" - to touch it is instant political death.
It needs reform, as it will not be sufficiently funded within "X" years - but no one, on either end of the political spectrum, dares to even mention it.
