Homeless and Downtown Condos

As you all know 2,500(so it seems!) condos are popping up in Downtown Nashville, where you can easily spot homeless people during day and night, especially around the Public Library.
And, it's only natural as more professional white collars move into Downtown, the city officials will help make the place safer by driving these eye-sores/potential-criminals(in many people's view) out. (i am so used to NYC sidewalks, these poor people don't bother me as much as inner-city teenage thugs.)
But where do they end up? They don't just die out like weeds. Actually, like weeds, they will keep coming back.
