The cost of socialism is a very good question...and one that will never be discussed in liberal rags or CNN, MSLSD, Daily Kook, Huffington Pest, or Dummy Underground.
The cost is basically incalculable. It's not just the many millions of ruined lives, deaths, wealth destroyed, etc.
It's an ongoing tragedy with many people still unable to grasp the obvious....socialism is the worst man-made disaster to ever befall the planet.
