"what if every protestor that showed up was an American-born citizen"
"what if?"
FYI, as a CA native, I can confirm that the most outraged about the illegal immigration issue are in fact American citizens of Mexican ancestry. These illegals are not only taking away jobs that have historically been done by American citizens of Hispanic ancestry but the illegals are also pulling down the wage scale of the job market.
And any American, no matter where their ancestry, knows that if they need a job there exists legitimate avenues for getting a job.
FYI, as a CA native AND American citizen of Mexican ancestry, I am not "outraged about the illegal immigration issue". There is enough in a healthy economy (and more importantly, American values of Freedom and Hope for a new life) for everyone here - what we should NOT do is anything to trigger another recession though.
