I go along with Maggie Thatcher:    “The problem with socialism is that you eventually run out of other people's money.” 

It applies to any taxing government and any country.  

There aren't enough of "them" to support all of the rest who want/need/desire to be supported instead of working.  

As far as Russia is concerned, 'Communism"?  Not now not ever.  It  was from the many for the benefit of the few when the Commissars were in charge and when Putin and his companions from the KGB/FSB took over, the main change is that they are now truthfully called oligarchs instead of Communists.
