Dallas (where I live near) is notorious for giving developers tax breaks to tear down lower class apartments if they agree to build something of much higher tax value. I doubt Dallas is odd man out. I'd guess that's exactly the worry here. Installing places like Trader Joes, which have the impact of attracting the more well-off, causes a gentrification feedback loop, raising the cost of local housing and ultimately displacing those that can't afford it.
