Did you try to get involved in creating one or work for one ?
If this is fundamentally a model you think if more fair and should be more popular, the logical step would be to get involved in this. Either it will be successful for you and you will be (slightly) closer to demonstrating that it's a viable alternative to the corporate/capitalistic model that dominates the economy; if you end up being able to quit your day to job to replace it with a coop job instead and reach/maintain a lifestyle that you are comfortable with.
Or it won't be successful for you and you will learn why it's not gaining in popularity despite this being a well known model.
