Comenting on van Parij's paper on "basic income capitalism" the author argues that the proposal for a guaranteed basic income in a capitalist economy faces the same dificulties of other proposals for the realization of non-economic values and preferences that are unwilling to give up the logic of the market, like investment planning or the taxation on pollution promoters. To supose that the distribution implied in warranting a basic income for everyone would not violate the economic market mechanism means to pressupose precisely the point to be demonstrated.
