Strawman alert - no one has ever said the U.S. has to feed, clothe, and shelter 3 billion people - I believe the current debate is about 20 million max.
No. Krugman wants us to feed 6 billion.
True enough. The problem is, that at the start of Operation Barbarossa, the invasion of the Soviet Union by Germany, the problem wasn't Germany. It was instead just "those first few companies of infantry, supported by the first few tanks".
When my throat infection started yesterday, it was only a question of those "first few bacteria". What, me worry?
Hey, lets just let all the worlds 8 billion in and then sort it out. How many is enough....100 million, 200 million? When will it be a problem to you?
Is it? According to you a couple days ago, you would like to see up to a BILLION new immigrants come in. Which leads to another question. There aren't that many people in Mexico, where would you like them to come from?
