The employees with children will most likely not live in Davidson County because of the bad schools. Williamson, Wilson and Sumner counties all have much better schools. You can pay $10-20k per year for a private school or hope you child is fortunate enough to get into one of the Magnet schools ,but most people choose to live in another county.
I don't know who the average person in TN is, but I get the idea we are an uneducated bunch when it comes to economics that is just trying to survive (like most places in the world). VW hired many local workers at a good salary when they first opened. When people were desperate for a job they were hiring people for $10-12/hr. I suspect that is significantly higher now. Chattanooga lost jobs for decades. I moved there in 74 and the air was nasty. The city is in a bowl surrounded by mountains, and the air does not move out of that bowl. The industries that were the worst polluters shut down, and Chattanooga is a much cleaner city now. But, they needed businesses to employ people. VW did that.
Amazon might get hurt by the new sales tax ruling, but others online retailers will also have to collect the sales tax, and Amazon already collects sales tax on what "they" sell. At least TN tax revenue should increase. Or maybe we are just honest people, and we already keep records and pay our use tax to the dept of Revenue.
