I know any number of people who would eagerly start a high risk innovation play as a worker cooperative, because the money reward isn't what they care about. They care about making change in society or seeing a technical advancement become wide spread.

For most of them, they just need the chance - a floor under their feet so they can't fall too far if they fail and enough funding to get going. And, given how much crowdfunding has succeeded in todays world of concentrated wealth - I believe crowdfunding could provide that in this system where wealth is much, much more distributed.

The other piece of if is, with worker cooperatives every single employee of the company is fully bought into that innovation play. And stands to see the rewards created by it. Not just the investors and company founders. If anything, it increases the effectiveness of these companies, because everyone involved in them is incentivized to give it their all. Everyone involved stands to see the rewards of success.
