What the MSM seems to ignore is the fact that population winds up, in the long run, as being the strongest indicator of a nation's ultimate strength.
Right now the US and Russia hold that title due to our nukes. But China, with its huge population, is gaining so quick that they will likely overtake us by 2020. India is a bit further back, maybe overtaking us by 2050. But population will be the deciding factor, and I dread the day that we're no longer number one.
Given all of that, it's obvious why these academic America-haters would bash having a large population - for if we're populous, we are strong, which cannot be allowed.
How strong exactly are countries like Indonesia (242M), Brazil (190M), Pakistan (143M), Nigeria (129M), Vietnam (83M), Egypt (78M), Ethiopia (73M), Sudan (40M), or Afghanistan (30M)?
The last time prolificness of the underclass was any kind of strength in the modern world was when Eastern Europe was repopulating itself after the second world war. Strength in the information age is not measured by number of ranks of fertile peasants.
