In my country, 2030 is foreseen as the year the public retirement plan administration system will collapse due to this.
Dismantling public healthcare is a solution our government is already going for to the detriment of everyone (unfortunately) but public retirement plans cannot be changed retroactively to any extent, they are reducing the highest pensions and blocking the rest of them (inflation will de facto lower even the blocked ones) while at the same time increasing the retirement age progressively but still it isn't enough.
