So.. the reason why your utopian version of socialism failed is because it was someone else's fault? Interesting take.

We do have a soft form of socialism. It's called charity and it's voluntary. Every other form is through legislation and has the implied threat of violence. We call that violence, enforcement because it requires the use of force.

When we threaten others with violence to take from them what they are unwilling to give voluntarily,, we have a word for that also.

The word is "theft".
