It's not a coincidence. The same .1% on 99% class warfare caused retirement age to be raised and life expectancy to be lowered.
The "pension affordability crisis" was patently never actually about pension affordability. If GDP goes up 400% since the 1960s while dependency ratios go up a mere ~15%, there's clearly something else going on.
That thing was a politically directed wealth transfer from poor to rich.
