This is a good first-order approximation. One generally admirable thing about American culture is that it's not acceptable to just inherit wealth and try to rule society. Where this backfires is that it means that rich kids get dumped into the mainstream labor market and, with their superior social resources, take most of the top jobs. VC-funded startups are mostly a mechanism for taking parental wealth and influence (a socially unacceptable thing for the child to live off of) and laundering it into shares of newly-created businesses, so that the sponsee looks like a genuine tech entrepreneur rather than the beneficiary of a managed outcome (acqui-hire!) put together by his parents' friends.
There is a lot of technology work, even right now, that improves peoples' lives in immensely meaningful ways. Perhaps the people doing such work are a "silent majority" of technology. The problem is that you never hear about it on Hacker News or TechCrunch, and the contemporary crowd of Valley king-makers runs away from it.
If something is worth doing, it's usually hard to do and even harder to control. If several of the constraints are socioeconomic arrangements (e.g. Joffrey must get at least $10M and a VP-level position in the inevitable acqui-hire; and we must let Squabbling Hen Capital in on this deal, with a board seat, because we owe them a favor) then it becomes a lot harder to actually do anything useful. Instead, it becomes "tech is hard, let's go Snapchat".
