That's because it is.  Current workers support current retirees minus what the government loots for other projects and waste.  With that structure and our decline in fertility,  the coming generations not only will have fewer workers the neoliberal policies that traded well paying manufacturing jobs with low paid service jobs and gig apps that don't generate the level income to continue the scam even with heavy taxation,  which btw also reduces fertility.

 If you're under, 50 start saving everything you can afford to. Also, beware of 401k/ira schemes. These are absolutely going to be taxed heavily and/or looted entirely by characters like Sen Warren to pretend SS is viable for a few extra years. Watch out for that in another 5-10 years at most.
