I'm not here to fight about one mega-data center where they are circumventing local control. I'm talking about the dozens and dozens of data centers being proposed and accepted by city councils all over the United States: https://www.datacentermap.com/

There will be some obvious bad deals. I think you're wrong to assume that the county is not broke from a municipal finance perspective. Nibley, Utah residents had their town evaluate by Strong Towns, they were in a fairly tough financial position until about 2015. The idea that you have residents that are even doing these reports mean that you have an electorate that actually cares at all.

The proposed Box Elder County data center would double the county's tax revenue, even with the tax breaks. There's a clear incentive for the county to approve it.
