This war is actually going to get some people out of business and send some back home, while it will also make some businesses stronger. But not only will it end their it will also extend down to the citizens, as everyone will suffer the increase in the price of products, which will affect them mainly, especially those who struggle to feed themselves. Only the elites will enjoy this war to some extent; the average person will complain.
Jobs are plentiful in the US just the US Citizens don't like those.
So they employ illegals.
Jobs might be plentiful in the US, and its citizens might not be convenient enough to do those jobs, but that's because they have other better options, immigrants are looking for a way to survive and will accept high-task jobs for low payment, but that's not what's being discussed here. Many businesses that can't survive this war will shut down, and their staff will be forced to look for jobs elsewhere, where the competition will be on the higher side for the main time and will be considered unemployed.
