Tech people keep trying to fix people problems with tech. ~47k people die each year in the US from a lack of healthcare. Other countries don't need Moore's Law to fix this, for example [1] [2]. Conversely, it's fine that Elon runs around as Technoking as long as the batteries are pumped out of Gigafactories at full speed. Technology fixes for technology problems, people fixes for people problems. We don't need more wealth ("The future is already here — it's just not very evenly distributed" -- Gibson). America is one of the wealthiest country in the world. We need quality of life floors and more equitable distributions of what passes for and enables wealth.
With all of that rant said, I really love Sam's idea about the American Equity Fund [3]. It's long overdue, and something that the Federal Reserve could administer today with FedAccounts as the target of distributions from taxes on productive concerns. Sam's a smart person, and I hope he can sell the idea with a pitch deck to those who need to be sold on it. The issue of equity (social and economic) has reached a crescendo, and it would do a disservice to county and citizens alike to let the opportunity go to waste.

Policy is written by the elected. Speak to or assume those roles. Provide covering fire for effective contributors who can execute on your mission and vision, just like a startup.
But yes I do agree iterating to improve public policy is important too.
Hence the organization of Sam's essay to reflect this.
It is good for society if the costs of goods and services decrease over time to allow a given income/wealth level to live a better life over time.
