There's no such a thing as consistent, long-term sustainability in economics. Everything changes, and with it, politicians have to adept. This is something they completely and utterly fail. They, and their cronies and masters, just want to uphold the status-quo, and that's exactly why we don't have nice things in this world.
Adapt, or be doomed to repeat history.
Speak for yourself I have lots of nice things.
But then again i'm not in this world.
