Consumer welfare and shareholder welfare are the same thing, the richer shareholders become the more cool goods and services are produced for the masses of consumers.
As a business owner or shareholder it's in your own interest to sell to as many customers as possible. The largest market in the world for any product is the entire world, all 8 billion of us. And so in reality, every new technology – even ones that start by selling to the rarefied air of high-paying big companies or wealthy consumers – rapidly proliferates until it’s in the hands of the largest possible mass market, ultimately everyone on the planet.
Your phone Panda... cool gadget.... cool for you cool for shareholders
