"As much" is my argument.
Those who say "They are getting free shit" are simply lying. Furthermore, all of us get "free shit". I didn't pay for I-17 anymore than you paid for I-10. I paid part of it, sure but all of us are warmed by the fires started by others.
Public education, military protection, health care (medicare, medicade, CHIP, and ACA subsidies), transportation, and assistance programs (welfare, food stamps, financial aid, school lunches, low-income housing, child care assistance, utility bill assistance,) science and medical research, and interest on the national debt are all paid by federal taxes. These are things that illegals do, or often, use, or benefit from, but are not paying into (if they are not paying federal taxes.) That /does/ equal "free shit" no matter how you want to shake it.
Bug again, how much of your paycheck are you willing to put in so that illegal's can stay without paying for those services? 10-20%?
