Many American youth have had a brush with the law--usually drugs. They attend these trade school only to find that no one will hire them because all you have to do is enter their name o a PC and the odds are high that a "Mugshot" record will pop up and "bang, they are dead for the job". The same employers(many of them), hire illegals and do not check their backgrounds. So, these young folks screw up and get what amounts to a life sentence. Easy to dismiss with words about how stupid they are, until it happens to one of your own family.
