But at the end of the day the 30% overhead goes to Apple. If there is some sub-market of apps where there is actual competition--where the companies making these apps are competing with each other and are driving their price lower--Apple's existence tacks on a 30% overhead to all of the competitors equally, meaning it is the user who loses out, not the companies. When a government taxes you 30%, the money is supposed to go for services or capital improvement products that eventually indirectly help people. That isn't how Apple hoarding this cash works.
