I haven't seen anyone that it does hurt, except for some investors. I don't necessarily agree with supporting the unions, but that is beyond the point at the moment. All of those dealerships are owned by the same person/family. The point is the same person has a ford and a chevy dealership and there isn't anything stopping them. Sometimes, they are right next to each other.
Same thing here;

Same people own a BMW, Acura, Cheverolet, Ford, Hyundai, Isuzu, Nissan, Scion, Toyota, Maybach, and a mini dealership. That is diversity. Even if they had a dodge dealership, I don't think they would have to go bankrupt now would they?
Let's look at it another way. Let's say that I buy a Subway franchise. I purchase the rights to sell their stuff and buy their products and use their name. In a few years from now, I look at the economy and realize that subway is not doing well. Their profits are down 48% and they are relying on creditors and investors to keep them alive. They are spending vast amounts of money and not turning any profits. Now, keep in mind, I am still selling sandwiches and doing quite well. If I continue the course and just hope for the best, then I am a crappy businessman, regards of how well I am doing now, because when subway files for bankruptcy and refuses to supply me with more product and the bankruptcy court invalidates my contract with them, then I have store full of product I can't sell and I should have seen it coming. The auto manufacturers didn't suddenly start to have problems. The long and short of it is that if you sell new cars for a living, especially if you sell one of the big three, you are taking a big gamble for long term stability right now. That is just the free market talking, no politics. The current politics don't effect any of this.
