>It's not clear to me how that's sustainable

If it makes you feel better, I'm pretty sure it isn't sustainable. (But I'm not an economist so take that with a block of salt.)

I don't think anyone has the answers. It's just some of us are honest enough to concede we have no answers, while others promote an answer that aligns best with their belief system.

"It'll all work out."

"It's the immigrants/blacks/jews/whatever dragging us down."

"Nothing's going to happen and we can all continue doing the work we always have."

"Burn the rich."

Etc etc.

Not a lot of serious attempts out there at even getting a hand on the issues, let alone fixing the issues.
