The puzzle of capitalism is that a company that won't spend to expand their network will happily spend $15 billion to buy a competitor.

As a worker you're mainly concerned about how many dollars you get for an hour of work, a capitalist is concerned about the return they get on investment -- they want to invest as little as possible but get as large a return as possible.

A consequence of that is that a huge valuation like what Apple has is a bit of a bluff. If they really started to invest that capital their valuation would collapse, their capital looks valuable because they can run a big business while using very little of it.
