> The benefit of billionaires existing is that they made extraordinarily valuable businesses.
Debatable depending which business, and also highly subjective. Amazon is valuable to Wall Street, yes most certainly. It also generates massive amounts of garbage, pollution, and human suffering. Are we including those in the value statement or are we going by the capitalist axiom that as long as the number went upward, the non-financial cost doesn't matter?
> If you create something (a company, a video game, other IP), and people value that thing at a billion dollars, then you’re a billionaire. Notch became a billionaire after selling Minecraft because almost 100 million people play it.
So the system works because the system is working? This is circular logic at it's finest. I don't care what Microsoft decided Minecraft was worth, they're an equally diseased part of a diseased system. It's like saying "this cancerous tumor isn't a problem, because the other cancerous tumor vouched for it." So what? I don't place value on the opinions of capitalists on the value of the capitalist system. Can you justify it without citing a capitalist?
> What do you expect should happen if someone creates a thing of value worth a billion dollars? Do you not want these things to be created? Do you not want them to be sold? (Ownership has to change hands eventually; people don’t live forever). How are you expecting society would work?
You're working all of this from the viewpoint that markets, capitalism, and competition are the only ways to generate stuff. Not only is that not the case, and I would cite the entire open source community as evidence to that fact, but I reject outright the assertions that:
1) The only things that have value are the ones where the value is expressed in currency
2) That the only arbiters of value are those who place values in the form of currency
There are tons of examples of things created with no monetization plan that are great. There are tons more things created with a monetization plan out of necessity, because without one they could not exist.
Again and again criticism of capitalism is met with this assertion that "well things have value and therefore we need to respect the market" and I flatly reject that. We're all locked in the same prison, every idea, every concept rung through this machine that decides whether or not something deserves to exist by it's ability to contribute to a market. A market built by people, allegedly for people, that is for some reason simply beyond reproach. Capitalism has ballooned to practically another religion, and you are a follower of it, so dedicated to it's holy texts you've entirely forgotten that human civilization existed for THOUSANDS of years before we had a bloody market.
Sod your market.
