btw, here in North Dakota, businesses were importing people from all over the world to work in retail, restaurants for a time because we had a severe shortage of people to fill the jobs available. Some I met were from Brazil and a number of southeast Asian countries. They came here, worked a few months and were rotated out.
And they didn’t work for minimum wage. No one here does.
In follow through on why the shortages you might consider how they advertised for people.....not that they didn't but where did they try to get people. You see it's a numbers game.....companies that recruit foreign workers know well how to play this. There's plenty of articles about how they abuse and mislead people in order to hire foreign workers when they don't need to at all.....
