From Von Mises’ Socialism:
The world inclines to Socialism because the great majority of people want it. They want it because they believe that Socialism will guarantee a higher standard of living. The loss of this conviction would signify the end of Socialism. (462)
It is true the world still inclines for socialism–even though they believe that it will not guarantee a higher standard of living. The reason is despite the fact they know that socialism does not work in practice (economically); they still believe it is the right thing to do in theory (morally).
