Rather a relic of the industrial revolution, even when applied to environmental products and services. The global business game has three problems. It aims at false goals. It has lost important steering mechanisms. And it wastes not only natural resources, but human resources, the creative participation of the people.
Market share is an abstraction.
You can't eat or hug, breathe or dance to these things. They are means, not ends. What we WANT is healthy children, good food, clean air and water, friendly communities, fun and joy and secure jobs that use our talents well. If we lose sight of those real goals, we find ourselves trashing the ends in order to pile up the means. Just listen to corporate leaders explaining why they must addict our children, put untested substances in our food, pour toxins into air and water, abandon communities and downsize or underpay us, all for the sake of dollars, stock values, market share.
