I think Lawrence Downes is off on the wrong rampage supporting the 14th amendment, to put it politely. The 14th amendment says any child born here is automatically a citizen. It was important after the Civil War, to protect ex-slaves.
World population has grown since the end of WW II from 2 Billion to 7 Billion. The US needs a much better safety net, but not for all the unemployed of the earth. We need to close our borders, and reduce income inequality, create jobs for the poor and minorities, strapped with police records and jail time. But other countries should take care of their own over population problem. The US should help other nations with sustainable development as much as we can. It is weird and improper, that Chinese fly to Los Angeles to have their babies, and then fly back to China. I am not a right wing quack, I am a moderate Independent, who is quacking harder and harder about climate change, sustainability and what is now called the 6th great extinction of species, which is caused by an over abundance of humans.
