The data center jobs are middle class. With progressive taxation, those 30 middle class jobs generate about 100 average people's worth of revenue. Presumably Lewiston has schools which could use the funds.
And presumably everybody in Lewiston already has lunch somewhere, so a new sandwich shop that was successful would put another lunch spot out of business, for a net zero jobs.
Edit: the larger point here is that jobs, particularly skilled jobs, don't grow on trees (much like money). New technologies and new jobs replace old technologies and old jobs. If you put a ban on new technologies and new jobs, you'll just have more unemployed people.
