The left has been railing against corporate subsidies for years, at least here in Minnesota. We've had all kinds of stadiums built on the public dime and outside of the construction jobs inherent in the building of the structures, the economic spin-off has been negligible. Of course, Ziggy Wilf and the Pohlads watched the value of their franchises increase markedly once a new stadium associated with the team was erected. Who was pushing for the stadiums? Downtown fatcats. The micro-left and the libertarian-leaning conservatives opposed the ventures.
What developments like the Amazon deal usually show is a re-location of business opportunity as opposed to an increase. If there's going to be a hot new part of town, somewhere someone else in the city is going to feel a chill. There may or not be an uptick in surrounding residential real estate depending on the quality of the housing stock. What usually happen is that renters are priced out of their properties and homeowners may be taxed out of their property due to their rapidly rising home values. It's not unheard of that properties are condemned by the city, homeowners are paid off at a price below what the true market would bear, and a luxury high-rise goes up. Development incentives basically work for the person seeking them and very few others.
