Yeah, but if you listen to the guy talking in the trailer you get the idea that he is an old man and possibly he is a business man because he has children and a big house as you see in the trailer.
Usage of the money we get from the missions, like buying safehouses wherever you want and business buildings such as skyscrapers, stores, warehouses (Vice City: Stories) and the ability to buy cars and have a family with children and stuff (not wannabe Sims) :D
