I support unions no question. Kind of weird though that there is no overlap pretty much between those who can start companies and those who want companies to share the wealth. There are millions of companies and basically none split profit equally.
Most employees appreciate that they are getting paid whether or not the location performs well. They don't get an equal share of the profit, but they also don't pay an equal share to cover losses if the business is not profitable for a season. If a Starbucks locations were closed for a month during peak Covid, would the employees be happy to (a) not get paid, but also happy to (b) still help carry the cost of the lease, utilities and other operating expenses?
If I start a business and my employees are willing to put their name on the loan (backed by their homes as collateral), then this is a different discussion.
They are more common that one may think. They have quite a foothold in e.g. European agriculture and even finance https://en.wikipedia.org/wiki/Mondragon_Corporation.
