There are very few jobs during operation. Mostly site security and a few tech support staff. There will be some steady work for maintenance contractors, but that's much less than the initial construction.
What would you prefer? To me, local communities tend to benefit in multiple different ways during and after these projects, poorer communities become richer, communities with little opportunity now have more opportunity. I’m always a bit baffled by someone saying “Please don’t invest $5B and create 100s of jobs and taxable improvements in my back yard”.
This is a common argument: wanting 1000s of jobs during construction and 1000s of jobs after construction, but this isn’t a car manufacturing plant. That’s a “we want our cake and we want to eat it too” argument — not saying it’s your argument just that this comes up frequently.
