Because the Supreme Court in their decision (Kelo) over a case in New London, Conn. decided that a business trying to engage in development useful to the community could take someone’s house. They also decided if I recall correctly that states could make their own rules on this. Here is a detailed explanation.

Kelo’s concept of “useful to the community” used to be, and still SHOULD be unconstitutional. It’s the biggest SCOTUS screwup I know of between Roe and Roberts. And Framers certainly didn’t intend what Trump and friends tried to pull in Atlantic City. My hypothetical comparison for the Donald would be this: suppose someone richer and more powerful than him, such as Bloomberg, wanted to tear down Trump Tower for a cab stand and asked DeBlasio to ED it for him. Should they be able to trump the Donald’s wishes on the subject or must they accept either Donald’s denial or his price?
His asserting that everyone always comes up fine is utter BS.
