people who set policy need to think of all consumers, not just the rich ones such as yourself. More working class people could buy iPhones if they were not artificially high priced.
You too would benefit from a competitive iPhone market, there would have been an earlier introduction of large screens, cheaper memory options, perhaps getting choices that included repairability, replaceable batteries, microSD cards, etc.
Think of it this way: if Apple was broken into three Apples that compete with each other, the shareholders would not have lost anything that they are entitled to: they'd each still own what they owned before a share of each of the new companies instead of a share in the old. But previously monopoly prices would drop.
