I don’t know where in the world you live, but here in the US there is a decades-long trend of people abandoning group social activities in favor of individual activities. Robert Putnam wrote a whole book about it called Bowling Alone back in 2000. Organizations of all kinds have seen declining membership, from adult sports leagues to scouting organizations to PTA groups. If you can find a group of people dedicated enough to form and maintain a club, then you are bucking the trend.
This sounds a bit like a normal non-profit organization, but the board of directors is composed of all donors (the “consumers”).
What’s the incentive for someone to want to be a “worker” in this scenario? I assume they are still paying dues? Are they getting some compensation for doing additional work, or is it an unpaid positions?
