Virtually no other country allows legal immigration during times of employment crisis’s unless it’s provable that you won’t be occupying jobs that citizens can occupy or you are self sufficient. As a matter of fact immigrants to this country are supposed to be self sufficient or return to their home countries unless naturalized.
I take exception to the notion that we need to import labor to do the jobs US citizens won’t do. I do and have done every job you listed. Working builds character and self esteem, traits sorely lacking in the US today. If we were to stop paying ner-do-wells to sit on their asses watch how fast those jobs are filled. There are very few illegals in my area yet all those jobs you mentioned are filled. You sound like an out of touch elitist snob to me.
Dirty Jobs, Mike Rowe. Plenty of Americans do hard physical labor every day. Even some who post on Free Republic.
