And these are the types of jobs that provided a decent living wage for the middle/lower-middle class, of which a lot of people in the midwest and rustbelt use to do, and the loss of such jobs has decimated these communities. Service sector, warehouse fulfillment, and gig economy jobs don't provide nearly the value, nor do they provide the types of benefits that former jobs did.

Edit - Not sure why my comment is being downvoted. A lot of the jobs in the midwest were things like basic factory work of plastic products, textiles, CNC machining, molding (of which my dad was previously employed doing), and other things of that nature which have been outsourced over the decades. These jobs not only provided a stable livable wage, but most of them also provided benefits such as health/dental insurance for not only the workers but their entire families. These jobs have left over the years, and nothing which provided the same standards of living has come into replace them. States such as michigan, illinois, ohio, wisconsin, and others in that area have been hit hard over the past few decades because of these changes in the global economy.
