The dis-ease is the current distribution of resources, which is a symptom or side-effect of capitalism evolving to its extremities - those systems can be influenced to incentivize different behaviours and patterns though to correct the dis-ease. If people believe resources are scarce, then there may be an issue. If people believe we have access - through human will, passion, and ingenuity - to the resources of the whole universe, then scarcity is only an illusion and we need not allow this fear to perpetuate, as it only leads to unnecessary suffering through fear of survival, and fear-mongers being able to control populations and create wars or at minimum perpetuate the suffering of one group for the gain of what they consider their own population.
This is a myth. Please refer to Deirdre N. McCloskey's work for a thorough debunking. The first two volumes of the proposed six volume set are available from amazon, the one you'll be interested in is 'Bourgeois Dignity: Why Economics Can't Explain the Modern World'.
Could you clarify or specify what it is you say is a myth and why it's a myth? A brief of what Deirdre N. McCloskey says would be very helpful and much appreciated - thanks.
Edit: Reading the Amazon short description, "[...] The result was an explosion in economic growth and proof that economic change depends less on foreign trade, investment, or material causes, and a whole lot more on ideas and what people believe. Or so says Deirdre N. McCloskey [...]"
That is relating to distribution of resources, albeit local resources.
