Being locked out of schools will have a very negative effect on students. Many poor kids will go hungry away from school lunch programs. There will be a significant increase in mental problems because of the number of people who are socially addicted and define themselves by their jobs. Blows to ego and a major loss of purpose, all that.
Many people will simply not know what to do other than watch their tvs and phones, kids included. Diet and exercise will both suffer and there will be a sharp increase in sedentary lifestyles with all the attendant problems like overweight people consuming too much junk food.
It will take regular routines, focus, and self-discipline to sidestep and avoid the above problems. People will simply not know what to do with themselves and their increased free leisure time.
