Time Person of the Year, 2006
It's $7 million over 10 years, so the net present value is less than $7 million. Furthermore, they're tax breaks, not all of which will necessarily be used or be extra (such is the nature of tax breaks). So the expected net present value of $7 million in tax breaks over 10 years might be only $3 million. It will be interesting to see how Carrier's parent company reports the benefit in its financial statements.
As to the benefit for Indiana, consider the difference between 1,000 making a good salary (and paying income taxes on that salary and sales taxes on the consumption that follows) and 1,000 people unemployed and on the dole, collecting unemployment benefits, and possibly welfare and Medicaid. I can't imagine that giving $7 million in tax breaks in this case isn't a great deal for Indiana.
Guess what, those people are all going to be unemployed after a year, so for $7 million Indiana gets a Trump publicity stunt with zero long term benefit. How about finding a company that isn't going to move anyway?
