True.
At some point, the inhabitants of the colony are brought into the system, and like I said elsewhere, you aren't going to find a lot of people living in cities in these places now who would be willing to go back to the lifestyle they had before the colonists showed up. What they do demand, often with justification, is their share of the modern world.
You honestly think people wouldn't want the luxuries of the modern world if someone wasn't forcing it down their throats?
Human labor has always been a commodity. In fact, it's pretty much the original commodity from which all others flow.
