I would say capitalism values ownership, not ideas.
Lol, this is exactly the kind of intellectual jealousy dude was talking about. This is the economic equivalent to "girls only date a$$holes.... under my system 'nice guys' would win by default"
OF COURSE capitalism values ideas. The automobile was an idea. The computer was an idea. The telephone was an idea. Using oil as an energy source was an idea. Google was an idea. Capitalism enabled the creators of these ideas to be appropriately rewarded. Socialism would NOT, and by extension would STIFLE ideas. The only idea socialism rewards is the idea that one person can't have too much more than anyone else, and that property differential is arbitrarily set by people whose ideas are not of much practical value to society.
There's definitely a lot this dude is not on the money about, but his point about intellectuals wanting to control everything is spot on. The concept of a world where the biggest activity (commerce) is decentralized frightens you. I do think there are aspects of society that should be more public/centralized that aren't.... particularly sectors where info is scarce and providers use that confusion to their advantage, like healthcare and insurance. But the simple idea that you as an intellectual can't have a say in every transaction or business relationship or paycheck is not something you are willing to accept.
Intellectuals need to stop pontificating over how to control everyone and start creating ideas that are of value to society. Thats the only way they will get the respect they feel they deserve.
