2. Job providers have forced the work they should put in to train people unto colleges and other institutions. So instead of coming to a place and learning the job they want you "finished" so to speak.
3. Immigration, not only in the way that they take jobs other people could take and drive down wages, but also that they give some jobs a lower status. For example, there's nothing wrong with being a janitor for a while but here in Europe that has become an immigrant's job, same with food delivery, it has become the old trade-hate our parents had but worse.
