Well duh. It's going to be easy to get affluent European college kids to work at beach resorts, where the social life will be hopping.
Getting them to pick apples or tomatoes in the country miles away from any nightlife is a whole other matter.
Getting people to come here and work is the least of our problems. There are plenty of poor people in Africa, for instance, who would jump at the chance to come here and pick apples and tomatoes, nightlife or no nightlife. There are legal means to get the workers farmers need. We do not need to resort to leaving our southern border open and hoping for the best.
