Do not underestimate your own life experience.
You've learned something by directly interacting with the world and watching it?
Try something on your own experience - is to know really, by your own feelings, not by books or TV. What can you know about the Soviet Union if all what you have been told about it - enemies words?
They lied to you.
USSR - at the moment the only socialist state in human history. The fact that it no longer exists - it does not mean anything. Now there is an alternative for humanity and the future, which means sooner or later humanity will step to the next level.
I would be interested to see the dialogue feudal and slave-owner. I am 100% sure that the slave-owner would find 1,000,000 reasons why slavery is better than feudalism.
However, after slavery came feudalism. After feudalism, capitalism has come. After capitalism come socialism. And so on. These steps are inevitable as progress, as evolution. They can not stop - unless humanity will be destroyed.
And sometimes happened that after the bourgeois revolution was restored the monarchy and feudalism. It does not mean anything.
Next socialist society would be deprived of most of the disadvantages of socialism of the USSR.
