I'll also point out that the vast majority of U.S. employees don't have ownership stakes and they still show up to work and work hard. Many people (retirees, the rich, other do-gooders) even work hard for organizations and don't get paid.
I appreciate your recounting of history though, and share your concern. The biggest fear I have is that decentralization of operations will make it easier for exploitation of workers on a small scale in secret. I also do share your fear that my understanding of how much resources will be needed is off because I grew up in a country where those resources were presumed.
But these fears are not enough to stop my work. Capitalism has led to my neighbors in the Bay Area being regularly shot, and that's a real problem I am dealing with today. So my concern over those shootings is greater than my concern about the theoretical future ones you are cautioning against.
You're wrong to assume that us naive Americans have no idea what it's like to see your friends and neighbors be shot for political reasons.
