My company is a worker-owned cooperative, which is a variation of the member-owned cooperative that you're describing, but has a similar goal of creating pathways toward ownership and encouraging civic participation. I actually have a parallel vision of creating networks of local cooperatives to help us build climate resiliency -- I'll be writing about this on Medium shortly, as I'm going to become a co-owner of my company this week! Thanks for sharing your wonderful vision and glad to see other people thinking along the same lines.
