All the megacorps (Google, Apple, Disney, Nike) are owned by the same asset holding companies (BlackRock, Vanguard, etc.) through a system called "Universal Ownership" where holding companies will buy 5-10% of the shares of every company on the market, giving them voting rights on the board. It doesn't matter if one of the companies on the market does better or worse, all the profits get funneled into asset holding companies. This creates a situation where none of the megacorps have to compete with each other to lower prices. It's a meta-monopoly
