Don't worry about a flame war, I will show respect to serious people who are making serious points.
The government mandate is to allocate vehicles in a fair and equitable manner. Therefore, the more a dealer sells, the more equitable they are, and the more vehicles they get. This has nothing to do with first come, first serve, or however he (she?) stated it prior.
Think about it this way. If "Joe" Chevrolet sells 300 vehicles a month, and "Dan" Chevrolet only sells 30, why would GM give them the same amount of vehicles? Allocation would then be for every 10 Camaro's Dan gets, Joe will get 100 because based on performance, this is the fair thing to do.
