Why would profitable businesses choose to come into this structure if they have to hand over 100% of their profits?

30% of the profit in a mature Commons Society goes back to the co-workers that made the profit. This straight-forward sharing of the bottom line removes the need for complex incentive schemes and creates a “domestic economy” in which all have a vested interest in increasing sales and reducing costs.
CEO’s no longer have to address short term shareholder returns but can focus all efforts on long term company success
It is a new way to retain the vision, coherence , employee capability & asset value of a business when owners decide to exit ( eg on retirement) rather than selling into the free market often only for their life’s work to be asset stripped
Money is not the only way of valuing any proposition. When a business is brought or bought into the Commons Society, company managers, employees, their families and communities get the full benefit every year of investment in their education, training, health, culture and food production creating wider community and personal wellbeing for all concerned. This continually expanding added value can be a factor in structuring a partial buy out or bespoke deals with insightful exiting owners.
