Vladimir Lenin ( 1870-1924) also presented and imposed welfare state called socialist Soviet union.
Moutse Tung alos introduced welfare state called communist china.
Both countries & systems failed and now doing well on capitalist system. They learned quickly.
In welfare system government supports every thing which fails due less resources. Capitalism flourished in the western world because its run by people entrepreneurs and prospered because competition brings progress.
So far few welfare states are working, Saudi Arabia, Emirates and Brunei, just because they have enough oil money, they day it dries up, welfare will dry.
Imran Khan in Pakistan is en cashing the term welfare because people are ignorant and gets drunk by word Medina, how he will run welfare, he doesn't even have money for oil or loan repayments.
Riasat Medinah population was just may be couple of thousands at early islamic era and new islam was prospering with money coming from conquered regions. But now, Pakistan with a humongous population of 250M and no resources. ?? Even oil will not be able to support this much population. what a dream to sell.
Imran Khan in his speeches is selling both Riasat Medinah term and Success of China's industrial age. Both are opposite of each other. So far he has not copied even one china industry policy or state laws. Just talk.
