>The entire point though is that they won't get built where they are taxed
I dont think this is entirely true. Maybe not the first wave of data centers, but there are a lot of factors that go into the cost calc and its possible that it would still be worth it to build them even if taxed.
He's not saying it's economically unfeasible to build where taxed. He's saying they'll simply build elsewhere where they won't be taxed.
About a decade ago, a bunch of data center companies got fantastic deals with my city (low/no tax). People are pretty upset about it. A few years in there was a report on how many people they employeed. I think combined it was under 10 who lived in the area.
