Sorry you have to deal with this. I bet that most of that would come out with some combination of rubbing compound, polishing compound and or a paint cleaner. From the picture, it looks like mostly paint transfer. You could try it youself or try a good detailer. Find a Porsche or classic car guy, they usually know the best deatilers.
As far as the haves and have nots, this looks more like a rude, careless driver issue. They hit your car and kept going. They just did not care about you. I know people who have plenty of money and would drive away if they thought they could get away with it. Some people just suck, it is not always about status and income.
