You cant seem to see the forest through the trees here.

Fast food jobs not being done mostly by teenagers anymore signals problems elsewhere. Trying to fix it by focusing on the practices of the fast food joints is the wrong approach.

If you are focusing on making fast food jobs better jobs, because more adults are relying on them you are focusing on the wrong problem. The problem is that the job market in general is so bad that more and more people have to try for fast food jobs.

Also, many immigrants end up working fast food now. Need to control for immigrants as well when citing age statistics. If someone comes all the way here to work in fast food because its better than what they had in their homeland, thats fine. And it doesnt mean we should do anything about fast food wages due to that either.
