>>>I’m a pure Capitalist!
Then you should respect property rights.
Illegal aliens steal welfare benefits. They clog up our school and require massive capital expenditures. They clog up our hospitals, particularly the emergency rooms, for free (or stolen) medical care (they walk out without paying). They now make up a large percentage of our criminals. They receive welfare payments and other social support services.
The rights of a US citizen have economic value. They take that economic value against our domestic laws. They are illegal. They are criminals. Most companies that hire illegals know that their Social Security numbers are not valid (the IRS tells them).
Upate:
Brickmasons and other tradesmen can hardly buy a job around here now. There is no shortage of Hispanics on jobsites though. Something has to be done about this.
