It's a fairly simple grad student exercise in differential game theory.
The identification of the "Elite" as predator to the "Commoner" prey's income is rather provocative; shows the mindset. Applied Math as Bolshevism...
But there is truth to it, as all feudal societies revolve around "Elite" (er, thugs) schemes to do just that: steal earned wealth. Typically by taxation, which is always a thinly disguised protection racket.
Which in the end is funny. Because the foreigners who wrote this rather simplistic little simulation probably wanted to vilify private investors as the Predator, when in reality it's people in government...who have accumulated far more unearned wealth then the Capitalists can dream of.
We've been here before; there is a germ of truth to it, but reality is far more complex and multi-variate. The early 1970s were full of garbage coming from Paul Ehrlich and Carl Pope about Carrying Capacity; that's where Environmentalism as Marxism really made it big.
But people like Julian Simon fought back and showed that the simulations were juvenile and missed adaptations that would make better use of existing resources and even create new ones. We have seen all of that happen in the last 40 years.
The politically militant foreigners doing this little noodle missed all that, or are merely propagandists attempting to resurrect the vampire of anti-human enviro-marxism.
I don’t think the people who produced this report are “politically militant foreigners”.
Like any good bureaucrat they didn’t start the study until they knew what the study was supposed to prove.
One final thought - since when has NASA’s Goddard Space Flight Center had anything directly to do with national socio-environmental synthesis other than on the orders of Washington based bureaucrats?
