Bringing in foreign workers destroys the normal law of supply and demand. Under normal circumstances, employers should be paying higher wages during the busy season. Thanks to foreign workers, they don’t have to, while wringing their hands over the situation. Trump is good at that.
It is amazing that Trump was able to jump though the hurdles to get those workers. Delays because of labor problems can cost. The delay must have been the main concern after it was learned the availability in the area was not there.
