Even when there isn't any rampant abuse people get greedy fast. Here in Alberta we have a new hard right wing party who favor economic isolationism (they don't want to federal royalties on oil and don't want to make inter-provincial transfer payments), environmental deregulation (while denouncing global warming) and want to repeal laws that prevent the propogation of hate literature... It would be comical if it didn't look like they might win a majority.
Times aren't tough in Alberta, anyone who is willing to do crappy work in a harsh environment (sounds like the Free Colonies doesn't it) can make a bunch of money without needing any skills or education.
Interestingly these are the same folks that are pandering to oil companies (sounds like union loyalists huh?).
I guess my point is when you look at Billions of dollars people get stupid and greedy, I can only imagine how fast things would go off the rails when the profit of an entire solar system is on the line.
