Socialism did not ‘go’ monstrously wrong.
Socialism IS monstrously wrong.
A good Socialist is a dead Socialist.
As Jefferson put it
"government is like a fire it must be strictly controlled for safety against its getting out of hand and doing great harm... government is force and must be feared and controlled accordingly."
Socialist have no fear of government and want it to grow like a bomb fire. if one little thing goes wrong with that bomb fire people die.
Smaller the government the smaller the fire and best for everyone
