Think of it as the 'Apple' strategy. The most money for the least effort is to have a high markup for the middle class and up while ignoring the bottom of the market entirely. If you release cheaper things for the bottom of the market this gets you much less profit for your spend and also many of your existing customers will opt for the cheaper versions. In medicine this is exacerbated by the fact that you do not have a nice range and market segmentation, you are selling the same product to everyone.
