Such a simple but potent symbol of the systemic failure of communist model: the Wall. Fallen, 20 years ago today.
The great physical manifestation of the metaphorical Iron Curtain, the wall accomplished a task unheard of in a free society - forcing people to stay. That communist regimes needed guns, concrete and barbed wire just to keep their system from dying from emigration is a simple irrefutable argument for the terribleness of their systems.
Celebrate your freedom today!
