@Everyone with a beef on the wrong targets
A lot of people who feel strongly about this topic often train their guns on the wrong targets. A nasty aspect of this exercise is the often demeaning stereotypes they have about their targets - the outsiders who have been declared guilty of "stealing" jobs.
America is a great country not simply because of its might but because of its democratic society which at different points of time has corrected itself for any inequities it bestowed upon its lesser citizens in the past. No other society in the world has taken such big leaps in such a short period of time (speaking on a civilizational scale).
Yet, as is expected from a democratic society, there are those who refuse to look past prejudices and biases formed from their limited life experiences. What's true for one bad apple must be true of the entire orchard!
One must realize that American capitalism is neither foolishly greedy to cut costs at any expense, even that of a basic output quality nor idealistically altruistic to prefer foreign workers from less developed countries for the sole purpose of improving their lives. Where you have a ridiculously cheap business (read Walmart) you also have one that offers quality at a much higher price (read Target). American shareholders are the buying customer who decide how much quality they can sacrifice for a cheaper product (read higher stock earnings).
All those who like to complain about jobs being "stolen" need to realize that none of the business decisions taken to hire cheaper (not always the case) foreign workers are taken in a vaccuum. When the American is wearing his investor hat, he wants maximum profit on his money but when he wears his "laid off for being no more valuable than a skilled foreigner willing to work for 50% less" hat, he wants to complain about how American professionals have been compromised.
Who's at fault? The greedy investor and by extension, American companies for not doing enough to recruit local talent or the complacent, neck-deep in self-entitlement employee who doesn't want to make himself more valuable to his employer? If you ask the resentful types, the answer will more likely be: "The foreign worker who is raiding our job market".
