The left pundits are correct that Trump will not save the Rust Belt or Appalachia.
Without a complete re-organization of society, nothing will.
What they don’t say, however, is that not only do they also have no plan to save these regions, they have no desire to do so. In fact, if these areas just disappeared and with them all the inconvenient “losers” of society, they’d be just fine with that.
This attitude explains why many of the inhabitants of those forsaken areas will be voting for Trump.
