You've answered your own question. What makes 7-10,000 get up and leave ?
A better question-why didn't the 7-10,000 DO SOMETHING to change their government ? Do you really think you are getting the best that country has to offer ?
There is a report saying 400K have crossed this year ALREADY. What's another 10K ? Face it-80% of the world lives in poverty. The US can't take care of everyone

This is neither a Blue or Red thing. This is an American thing. If you can't see the difference, I can't help you.
