Kicking some 80 yr old couple out of a Victorian home in a decent neighborhood to build a hotel, health club and office building is not for the good of the public. It's for the good of the rich bastard that pays off public officials to get what he wants. Those ppl don't give a fuck about if they get fair market value, they want to livbe the rest of their lives in the home they raised their family in, the home that has all their memories
I could see in the cases where they are taking a shithole part of a town and trying to fix it up, but that really isn't what will be happening most of the time. Developers want decent areas to build in where ppl have money to spend..
