I understand your point that the average working stiff might experience wage loss or lose their job altogether, but I'm not sure you're considering the benefits to consumers, which is another role of the average working stiff.
I implore you both to read and listen about it (google/"lump of labor").
Does this statement also seem true?
"It is hard to believe so many * economists * don't "get it". You cannot inflate the supply of labor, regardless of the means, and get a good result for the average working stiff."
What do we think economists are doing with all their data sets and papers and conferences and stuff?
Second, the idea that immigrants and women getting jobs is a major factor in 40% of Americans not having significant savings is so completely ungrounded in reality or even popular thought as to make me wonder if you're being deliberately dishonest.
