if you have good skill the overpopulation and misery of others can fuel your wealth
I remember getting told a few similar statements. "Everyone has a sign on their head saying 'I'm special'", and "Every person you see walking down the street is a wallet".
IMHO, a large population only becomes a problem if resources are not managed properly and if you allow the population to be a liability (not disciplining and training them).
The sense I get from most of these earth-is-gonna-die eco types is "
There is just the right number of me and way to many of you." They can make careers out of trying to figure out how to stop the darkies from breeding and often they do.
The problem with 'over populations' is that people get what they need to survive. Total spend is cost/head * heads. Twice as many heads means half the profit from one's pineapple plantations. You can reduce the cost/head, but you get closer and closer to revolt then you have to spend a lot on paramilitary operations and the like.
Kissinger('s people) captured it pretty well in
NSSM 200 From wikipedia:
The basic thesis of the memorandum was that population growth in the least developed countries (LDCs) is a concern to US national security, because it would tend to risk civil unrest and political instability in countries that had a high potential for economic development. The policy gives "paramount importance" to population control measures and the promotion of contraception among 13 populous countries to control rapid population growth which the US deems inimical to the socio-political and economic growth of these countries and to the national interests of the United States since the "U.S. economy will require large and increasing amounts of minerals from abroad" and the countries can produce destabilizing opposition forces against the US.
It would be a good idea for the 13 countries who were specifically named as targets in the above memorandum to pay particular attention the the vaccines that the cooperating agencies (UN, USAID, etc) are bringing in, though it looks like their efforts on the 'injection' side of things have been adopted for world-wide use. The nature of the effects they have on differing populations is adjusted accordingly. In the U.S., for instance, giving people non-lethal ailments requiring life-long prescription drug use makes sense because the peeps have money to shake out where in less wealthy countries there is not point. Just sterilize them or get them to die off quickly.
By the way, the reason why so many people can make a pretty good living working on depopulation programs of various sorts is that the likes of Kissinger are behind it. Money is not one of the resources that his class lack...and they have a set of ethics which propels them forward rather than holds them back when it comes to eugenical implementations.
