How will Prout give all people the required purchasing capacity?
In a proutistic setup people will earn their required purchasing capacity through work. There will be no unemployment in such as progressive-minded socio-economic setup as local people on the local level will control the economy. When local people control the economy there is no chance of outsiders exploiting the local people. That local non-profiteering economy will develop self-reliance and it will be easy to keep everyone employed in such a consumption-motivated economy.
