Not all. I strongly hold to the view expressed by D H on that subject.
This is a bit tangential, but I generally don't like to frame the issues in terms of "overpopulation." The problems tend to be scarcity of some kind, ineffective social organization, inappropriate resource utilization, underdevelopment, and so on. The big umbrella term "overpopulation" doesn't do much for me and I don't think that the good solution is to campaign for less people. From the exposure I've had to the issue I'd say it's a very complicated topic.
And damn it, people reproduce. Waste gargantuan resources blasting people off to Total Recall and in the meantime those people will be replaced. I mean, if that's the whole strategy. If the strategy involves other things then why not simplify it and forget about the extraneous space ghettos. I'm very much pro-freedom and all that but I think I would prefer draconian social controls to such an absurd and wasteful project.
P.S. In anticipation of the inevitable misinterpretation, I'm not denying the concept of overpopulation. I think the idea of carrying capacity is valid and that overpopulation can occur. I'm saying I think the concept is overused, generally too simplistic, of dubious applicability, and in the end not very useful. It's also a bit charged and has misanthropic connotations that may limit its usefulness for sociological reasons.
