Right now, there's some Mexican guy who wants to steal your job. Your job! He doesn't care about you. He only cares about himself.
Do you think he needs your job? Do you think he needs it? There are plenty of jobs in Mexico. He could be making sombreros or selling tacos, or whatever the hell they do around there.
But he wants your job. He wants it because he's an asshole. He moved here just to make things worse for you, and now he's ready to steal your job.
And once a job is stolen, it's gone. There are a finite number of jobs in this country--138 million. When we add a new person and give him a job, someone else loses one, and the unemployment rate increases.
A smaller population results in a lower unemployment rate. If we were to exile 10 million employed people, it would create 10 million jobs for everyone else. Exiling 100 million would be even better.
When the Puritans got here in 1620, there were 138 million jobs for 102 people. The average person had over a million of them. In fact, they had more--because there were no liberals in the country. Liberals increase unemployment. When they make decisions, jobs are lost. The pilgrims probably had about a billion jobs each.
