Here are some numbers in support of my prior post, which roughly said everything will turn out OK since there will be an enormous world middle class.
"The global middle class is rising faster than expected, in numbers and in wealth. Last year 70 million people joined the emerging-market middle class, with incomes between $6,000 and $30,000. "
"The Chinese bought more cars than Americans did last year, and India has as many Internet users as the U.S. does. By 2030, more than nine of every 10 mobile phones will be owned by people in the developing world, with India and China leading the way. Coca-Cola recently forecast a doubling of worldwide revenues to $200 billion over the next decade, thanks to another 1 billion people expected to join the middle class by 2020."

By the way, the world "GDP" fell last year. That is why it is so impressive that (if?) 70 million people joined the middle class.
I won't add anything into Moe's bizarre natural ditch digger theories aside from everything he is saying is neatly refuted in great detail in many well established fields of research. Since he is clearly aware of none of them I would suggest beginning with the popular book Guns, Germs and Steel.
