No banks means no jobs, bad housing, no tools, no pc's, no security, no stores - but that dosnt matter, cause you dont have any money either, bad food, no mass production++
Most people commenting in this tread has no concept about what finance is and does, so it must be inherently evil.
Well, the world is more complex than that. Without finance your standard of living would probably be below one tenth of what it is now -unless you already live on the street of course. But then you wouldn't care because you'd probably be a alcholic or druggie. You won't get hold of any drugs or boose either so your fucked as well.
Tldr; The world runs on debt & oil. Get used to it, it isn't going to change anytime soon.
