Like it or not, we have nation-states, not a global labor market. The government of EVERY country in the world is elected to take care of their citizens. Why should the US government worry about wages of Chinese citizens - Chinese people have their own government, no? BTW, the US is already very open (close to 15% of population is foreign born, the highest in a century). In an economic crisis, it is not unreasonable to slow down immigration a bit. Also, it is ironic that you use the example of China, perhaps the most protectionist major country in the world.
