Yes, Population growth is the 800 pound Gorilla of Economies,
but NOT in the Positive way that Economists claim.
While population growth does increase GDP it usually
DECREASES GDP PER CAPITA. As the USA grows in
population, (from e.g. 150 Million in 1950 to 330 Million today)
the Middle Class gets poorer PER CAPITA
Solution: impose a zero-net Moratorium on Immigration
(which would still allow appx. 150,000 of best and
brightest to enter annually) See. http://www.carryingcapacity.org.
