Worker Shortages / Desperate Immigrants

How are we so short of workers while there are so many people trying to get to the US to start over? I'm sure most of the people from Central America, Haiti, wherever would be more than willing to take vaccines & wear masks if it meant they could get good-paying jobs to help their families escape desperate circumstances. We really should create a "pathway to citizenship" for people willing to contribute and be good citizens. I don't get it.
