The country was originally designed for 500 million. It was a lot quieter when there were 150 million--must be said.
Hell, everything was quieter until the hippie b@$tards came along. Them and their pot-smoking, communist filth are repsonsible for the majority of the woes we have in the world today.
Between 150 million with the Communist, Biggovernment mindset and 500 billion with a traditional hard working, God fearing patriotic ethos, I'll take thee 5 any day.
The problem isn't numbers, it's ethos.
