Thanks a ton for your thoughtful response! This article is actually not the only tax on childless people I've proposed. In this other article I proposed estate taxes on childlessness to fund educational systems that can employee early childhood parents.

"your specific proposal introduces shareholders into a worker-owned collective who are not well-prepared to make decisions for that collective. It weakens the workers' voices" - I disagree because you seem to be comparing my idea with current worker cooperative structures encoded in various laws in various states in the USA in which all ownership & control resides with workers. However, evidently (and I say evidently in terms of evidence), this type of business structure has not succeeded in becoming more and more popular. I go into the reasons why in this article, and into why my proposed alternative that allows for a minority of shares to be owned by passive investors (like workers' parents) might actually enable worker cooperatives to succeed against current corporate structures.
