Moreover, I'd be interested if anyone has actually done a comprehensive study on total value (long-term economic and short term investor profits) added/lost from startups. I wouldn't be surprised if we found something that looks net/net negative or even pretty small.[1] (That is startups globally, not just VC funded or SV startups.)
If startups are engines of wealth re-allocations rather than drivers of long term economic benefit. Well, then silicon valley is just as bad as Wall Street.
[1] We're quick to count the successes, but struggle to count the failures. More than that, many startups, as the author points out, are entertainment companies that don't add much economically. Finally, how much money is churned out of investable capital into acqui-hires? How much of that delivers a meaningful return vs. defending a market position?
