The people cosplaying here by repeating the values that Peter et al want them to quake will be the ones left behind.
What inequality does is ensure that there will always be two markets of consumers: one that needs goods at low prices and one that can afford higher prices for luxury goods.
As long as the lower price market exists, hoarding sufficient wealth guarantees you’ll be able to at least afford the minimum standard of living, allowing you to safely retire. If everyone was wealthy everything would be expensive and then no one would feel wealthy enough to retire.
...what if "health care" is viewed as a luxury good as it is in the statse?
There was even a leaked secret recording of heads of banks, where they basically agree that the party is coming to an end for Western Europe (due to demographics) and admire Merkel and Holland for hinting that to the population, as opposed to ignoring the problem altogether.
United States is the country that's most likely to go to shit. All of us wealthy professionals here are sitting on a powder keg of inequality and delusional politics, and nobody will be decoupled from it when it blows up.
I plan to stay for a few more years, then return to my safe North European home country with a solid stash of savings. My kids can go to good schools where teaching is in their native language. When they get older, they can go to free college if they're willing to put in the effort. When I retire, I won't need to worry about exhausting my savings because I've got a home fully paid and a sufficient baseline is guaranteed from the national pension system. There doesn't seem to by anything that would make me want to stay in America — perhaps the worst place on Earth to retire.
