I find that many of the people who don't see a problem with the current situation haven't been affected by it . . . yet. They still have decent-paying jobs, and they enjoy paying very low prices for items at the discount stores. The false economy in that situation is that, as "low prices" continues to be God here, more and more companies will look to improve their competitiveness by switching from more-expensive Americans workers to low-cost illegals and foreign workers. If the loss of jobs hasn't hit you yet . . hang on . . its coming.
I had this debate with a local radio talk host and his university professor guest. They don't see the problem of under-cutting American wages, because they haven't been affected yet. But, as the talk host's salary is paid with advertizing dollars . . and Americans continue to lose better-paying jobs and thus are less able to purchase the advertizers' products, maybe one day the talk host's income (or, more likely, that of the person who follows him) might take a hit.
Same with the university professor -- she gets paid so well because people are still attending college and paying heavy tuition fees. But, as the value of a college education continues to decline (as more high-tech and professional jobs are taken by immigrants and out-sourced to other countries) and people just aren't able to pay those high tuitions (plus, the money paid by government for higher education continues to decline, due to drop in tax revenues and other things . . such as the cost of elder/health care for an aging population . . that compete for those dollars) . . . the day may come when fewer profs can be hired and/or those that are hired are paid less. Again, this might affect future faculty more than current profs.
I worked for local government, so my job is fairly secure. But, I see how tax revenues have fallen as companies leave the community and state, and this affects budgets. Where I work, staff size has declined through attrition . . fewer workers doing more work. And, the cost of living increases and bonuses were not paid the past two years. I watch the city council meetings, where they discuss how many police and fire positions have been eliminated due to budget problems.
We all . . even those more insulated by the decline of American jobs and wages . . . are eventually affected. Do we really want to wait until we're all sitting in the sh!t hole?
