Hmmm
50 data center workers? How many of those, apart from the janitor and canteen burger-flipper etc, will actually live in the "poorest county"? Perhaps that will create 20 direct in-county jobs + provide an extra half acre for the lawn guy to mow and an extra week per year of landscaping jobs. For that employment stimulation, Apple is getting 4.6million per year?
There will be some building/installation work. But again, most of that will likely come from out of county and is not on-going. These days "building a data center" really means "Where do I offload these containers?". Thankfully the people that live in poor counties can't afford lawyers to chase away ugly data centers.
If I was a smaller business that really creates a lot of business and employment opportunities for "the poorest county", I'd be really annoyed that I have to pay full taxes to subsidize this exercise.
