You gave the right answer "when industry is forced to pay the right money". Your rationale is flawed because even if you hope for all illegals to be deported and as you've stated we don't need any more people in the United States ,globalization is alive and well and industry (corporations) who are publicly traded will move manufacturing, etc to other places to get the salaries they feel will be best for the company and its shareholders. So industry will never be forced to pay more then they think a job is worth. Trump didn't bring back manufacturing plants and jobs from overseas but he did have an effect when some companies moved some operations of their supply chains to other countries. Capitalism and supply and demand theories work but there working in a global setting, America will lose if it tries to go it alone, Impossible.
Wrong, because not all industries can move overseas. Most companies desire to produce near their customers. Transporting products is a huge cost. Globalization is not a new concept. It's been happening most of my life. Industry started moving out in the 70's when unions began getting greedy which made our products in the store more expensive. The workers got more money, and the unions got more out of their paychecks. American consumers started getting cheap and buying foreign made products.
For the industries that remain in the US, supply and demand works quite well unless you throw a monkey wrench in the system like illegals. If an employer can't find workers, they have to increase their offer, and that's how wages naturally increase.
In this country, we have a totally opposite view of the economy than let's say Europe. In Europe, they have solidarity with their workers. They buy their own products at any cost. In fact Italy was the hardest hit by Covid at the beginning. Italian consumers resisted buying any product unless is had a Made In Italy label on it. It's illegal to put that label on any product unless it is made in that country. Like we do with Mexico and others here, they brought in foreigners to do the job for nothing. They can produce products cheaper, and still be able to put the Italy label on it. Their foreign workers were from China, especially from the Wuhan area.
