Carrier didn't get bags of cash to create a handful of jobs.
It's a thousand jobs at an average of $31 per hour in wages, not to mention benefits.
It's up to $7m in incentives spanning ten years.
The jobs are worth about $850 million to $1 billion in total compensation over ten years. The $7 million represents less than 1% of that value. The income taxes, sales taxes, local spending, etc, etc, etc. is worth drastically more to that community and the state than the tiny $700k per year incentive.
Firt of all, it's much less than a thousand jobs if you discount the white collar managerial jobs that were never planned to be relocated. The number of overall jobs saved is around 800.
Of those 800, a significant number of them will be eventually automated or are already in the works. So your ten year figure is, in my opinion, a bit overly optimistic.
It was a symbolic show. Even if Trump did a Carrier-type deal every month for his entire presidency, it would be far less than one percent of jobs lost due to automation and offshoring in the past 20 years.
But the same company is planning on automating away jobs in that plant and closing the Huntington one. So it's not 1-to-1 gains here. The reality is Carrier is placating an administration for larger contracts (parent company of Carrier).
