I'm having a hard time responding to someone who's using a South Park episode as a discussion point. Like how can I debate a point made by a show that makes content reacting to the popular perception of certain ideas? That's like 2 levels removed from the actual true details.

Anyway the difference now is that those companies still exist they just take round after round of private investor capital and the employees are offered shares that will never be tradable. Were those businesses would go bankrupt in a few years before now they can take 5-10 years. Time value of money being a thing, your money will be locked up for longer in a bad investment than it would on the public markets.
