I think they're selling because they're not trying to do everything that makes money, but to concentrate on the things that are the most profitable. For example, you could make money washing dishes, but for most people, there's more profitable work that they could do, so they don't work as a dish washer. To prospective buyers- would you rather be a dishwasher or try for something that's even more profitable?
