Insolvency and prohibitive costs aren’t a hypothetical but have already arrived when it comes to elder care. And it will get worse. Class warfare is a thing but it is not every thing.
No, SS is not insolvent. And on the topic of elder care being prohibitively expensive, it's quiet simple: you can bleed the old dry because they don't have options. Meaning, it's not a free market, so any notions of competition vanish.
It's a problem with healthcare as a whole and that's why we see so-called "free market" healthcare fall apart. It's not a free market, and actually it is impossible for it to ever exist as a free market. Those same problems are amplified when it comes to elder care, because they're even more desperate.
I mean, think about it. I get chest pain and shortness of breath: which hospital do I go to? There's a market of exactly 1: I go to one hospital, whichever is closest and I believe has the best odds of caring for me. So there goes your free market, you actually have a monopoly. Despite the fact there are thousands of hospitals.
