So when the higher skilled workers at an Amazon, Walmart, etc do something to increase the company's bottom line resulting in more warehouses and stores being built, what type of workers are required to fill those warehouse and service positions? It's a symbiotic relationship.
"We're" not seeking reduced labor costs, the business industry is, which conservatives never run checks on. Conservatives can't have it both ways. Either you celebrate the increased profits for shareholders and owners (which eventually translates into overall GDP growth, i.e. "wealth creation") reduced labor costs illegal and legal immigrants help create, further resulting in lower prices for consumers.
Or you crack down on both forms of immigration, but agree to stronger labor unions, increased wages, and raised taxes on the wealthy, since the native born American standard of living is typically higher than immigrants (if it weren't, or if Americans were willing to lower their standard of living, you wouldn't see all the hand-wringing about wage suppression. Not to mention, Chinese and Indian tech workers won't be under six figures of student loan debt by the time they enter the job market, nor will they likely have extended family members to take care of here, so I don't really want to hear the deflection, "well, millennials just need to stop spending so carelessly on smartphones and Starbucks. Millennials actually spend quite frugally due to the aforementioned reasons).
