Well, you are right that socialism is an ideology that emerged in a society were commodities were touchable.  In todays society when knowledge/education and service is an ever increasing "commodity" some would say that this makes some of the old political ideologies irrelevant. I do not think so.  As long as knowledge and services can be converted into money and hard currency the old rules still apply.  One aim, is the equal and free distribution of education, another is to redistribute the tax revenues the state gets to the lesser fortunate in society.  

As long as knowledge generates money they can be redistributed.
