eminent domain

I believe that eminent domain is okay as long as they are using it for meaningful purposes that benefit everyone. Many times the government use eminent domain to their advantage and built for private purposes. I think its okay if they were building schools or hospitals, but not for private purposes for example, extending a parking structure for Mercedes Benz. There was an incident where Mercedes Benz wanted to take out a diner  in order to extend their parking structure. There was a controversy because this was a private purpose that wouldn't benefit everyone. I think that people would have thought differently, if it would have been used for a new school. So I think that eminent domain has been abused and that if used, it should be used for public purposes.
