In 1950, the US population was half of what it is now. That means twice more space per person. Less demand for land thus cheaper housing, emptier roads, more space for growing food thus lower food prices, etc. etc.
One area of population growth that is often overlooked which has exacerbated the problem. 100,000 Martian-Americans in Area 51 (nearly three time the amount of martian -amercans in 1950. 200,000 Transgendered-Americans 450,000 Domesticated-Canine-Americans registered to vote as Republicans 550,000 Neanderthal-Americans, mainly located in secluded mountain regions of West Virginia
In Los Angles we have Mayor Villarigossa telling us to conserve water... I always want to tell him if he wants enough water to go around, he can send back a couple million illegal Mexicans to that shithole Mexico... We built up a great water infrastructure then this bullshit government brings in millions of people illegally and tells us to conserve.....
Actually in 1990 the US population was 151 million. In 1950 it was 76 million. Today its just over 300 million. so the US population was half what it was 20 years ago. http://www.infoplease.com/ipa/A0004986.html
