giving developers tax breaks to tear down lower class apartments if they agree to build something of much higher tax value

I'm having trouble seeing how this is comparable. It sounds like the Dallas example involves (ab)using eminent domain to take property away, but the TJ case is developing new on a vacant lot. And the Dallas example is giving extra incentive through the government to do something that may not be economically wise on its own, but evidently TJ thinks that it can offer something in that neighborhood that will be able to justify its own existence.
