I know the people involved in the original MID company, and well remember the problems they encountered. The company and its owners were very active in supporting Detroit's music scene. It was eventually very tough going for them, and the company went under. Ritchie's involvement revived it, and it does indeed employ people.
During the 90s Ritchie did some session work for one of my partners, and one of his bandmates does session work for me. I'm well aware of the good he's done Detroit's music and non-music communities. Evidently he's a very good guy to work with.
You may or may not like his taste, but Ritchie is quite skilled as a musician (and rarely shows this off). I know of session work he did before he became famous, and he was damned good.
You may not like his means of expressing himself - I don't either in this case - but I'd be very surprised if any of the critics in this thread have done a hundredth as much for Detroit's community and for charity as Bob Ritchie.
