About $20 million of the $100 million represent cash. Another $15 million in abatements can't be counted as a cost as it presents money the government would never have collected either way. No company, no taxes. The $65 million in training does represent use of tax revenue.
Thats a total investment of $85 million for 1,000 jobs, or $85,000 per job. If the plant is in business for 10 years, that about $8,500 per job. Considering the taxes collected from workers at the plant including state income tax, sales tax, property tax, etc. The secondary benefits from employment for supporting workers and businesses and their resulting taxes. And, finally, the taxes paid by the company, seems like a fair trade.
As federal money will probably pay for much of the job training, federal income taxes from the workers, the company itself and supporting companies and workers, that will be reimbursed, as well.
Then, there's taxes paid on sale of the vehicles.
You're correct, though. Some people never learn.
