to start out at a minimum wage job and gradually learn the job skills to get paid more
Can't. Illegals took all those jobs.
Immigrants have ALWAYS taken the jobs that more established Americans didn't want to do! That was the case in the 1800's and it is still the case today. Today they are referred to as "illegals" but in essence they aren't any different then those who came before them. What is different now is that we've created an entire "sub-class" of Americans who have no desire to work yet still demand that their "needs" be met.
