Your table is interesting, but percentages don’t tell the tale. 38.7% of native born is a heck of a lot more people than 56.6% of immigrants, and the big difference is that immigrants work their way off welfare.
I speak from close experience. I work closely with this demographic. What really chaps me are the native borns who pass the entitlement mentality down for generations. I see it often.
My original statement stands. Mexicans work their tails off at minimum wage jobs. In most cases, any assistance is just that — assistance when the paycheck doesn’t stretch. Assistance, not support.
Compare that to a large number of born-in-the-US citizens receiving government assistance who will not work or can’t keep a job because of attitude or poor work ethic.
