Yes, all true, I live in a rural town and can attest to that. But that's 20th century abundant oil and we haven't caught up with the new paradigm yet, we have so far simply printed over it. When the oil goes, so will many of those jobs. Many are going now actually, it's why the middle class is contracting. Add in a financial collapse and it's off to the races for professional jobs. I saw a glimpse of it in the GFC, middle management got hammered.
Consider the example here @ 6:10

When I was young there was one University in my city of origin and one technical college. Now there are a dozen churning out degrees. That's the capitalistic model, the new ones were all funded by pay as you go student debt. The city was full of manufacturing then (1970's) but that's all gone. Gone too are the market gardens that surrounded it. A vibrant new city, all built on Debt, hundreds of thousands loafing on welfare. The only thing I can equate it too is the city of Rome in latter days of the empire. Of course it's a lot worse in America, there they have racked up, Corporate, state, Federal and Personal, around 100 Trillion dollars worth of postponed reality.
