That’s ridiculous; look at how many people “bettered themselves” with education (NOT in basketweaving) just to see those jobs outsourced or foreigners imported to take them. I see a lot of that in finance and accounting; many Asians (particularly young women) are taking jobs for which there are countless American candidates.
You seriously underestimate how determined most employers are to replace EVERY American on their payrolls; this is part of scaling back our standard of living to a Third World level, and it has gone on for years. It is no accident that Trump and Sanders are doing well; most Americans know neither party’s hierarchy will help them with this - in fact, more and more Americans realize they are both COMPLICIT IN IT.
