A remarkable transformation has taken place in USA.
At one time the word ' socialism ' was regarded with horror there, and to call oneself a socialist would be making oneself an outcast.
But the victory of Bernie Sanders, who calls himself a democratic socialist, in several states in the Democratic primaries is a significant event. It has made the word ' socialist ' respectable in USA, dsespite the fact that Hillary Clinton will win the Democratic nomination.
This has happened because Americans are facing a recession, and unempoyment, and many Americans have realised that socialism is not all that bad, and that 'free' enterprize has created many problems. Gross inequality of incomes is just not acceptable.
