> The other option, that you conveniently ignore, is that cities build a good infrastructure that attracts talent and the businesses come to either serve the talent or employ the talent -- no subsidy needed.

How do cities pay for that good infrastructure? either with tax revenue or debt (bond). Very often cities want to attract businesses precisely because their commercial base is in decline, with very little room to hike tax. As for debt, such a city may have low credit score making it hard to get loans, or being saddled with high interest rate.

Giving incentive to businesses allows them to stabilize long term revenue, at the same time adding local jobs. That's the theory. The reality of course include both good and bad examples of such scheme. Foxconn is a bad example.
