He leaves out that it's workers' labor that "develops and de-risks" the business, not magic capitalist brain power.

But aside from that, he's just doing that thing where liberals explain capitalism to you, and when you say "I know how it works, I just disagree with it and think we should do something else" they explain it again. Like, yeah, privately held capital and economic competition means starting a business is risky and not available to everyone. I don't understand how they think that's a good argument for capitalism.
