retirement system is the global problem that will have to be taken down if the economy as a whole is going to survive and be just to current generations, it was always a flawed system built on this notion of endless growth, maening it's the reason why zero growth in economy or in population is an impossibility and why politicians no matter the party always focus on it even if they require destructive policies like immigration, if you take that away a nation can survive even with decreasing population or shrinking economy
