In the following sentence I agree that the men you mention where gangsters, but from there I must share I do not agree that they invented socialism.

"That socialism of the 21st century was invented by the gangsters from Fidel Castro to Chavez and Maduro with all their henchmen.... ."

The following sentence manifest that which does not exist in reality.

"Socialism as such JAMAS has worked or will not work because the same socialism contrasts with how the human being is: SELFISH by nature."

In reality Socialism cannot have worked because it never has! The fact is that socialism always goes to a democracy, which destroy's itself just like VENEZUELA has and still is. This makes my heart grieve.

Contradiction I have noticed do not actually exist, but when we perceive them if we are honest we discover it is some miss comprehension, which by the way leads to a miss understanding (wrong acts). Socialism is actually in a sea of these. One cannot in reality separate the difference between a gang of murder's and the so called authorities, because there is no difference.

We The People see this in all forms of Government.

"because the same socialism contrasts with how the human being is: SELFISH by nature."

If you think about it with the data given to you by those who have lied to you and your ancestors than the above quote from your post is correct. The individual looks inside their own self and ask the question am I SELFISH by nature. This question can only be answered by each individual. If you are, what course of action will best serve the selfish nature? If you are not selfish by nature, what is it that you truly desire.

The funny thing is that using logic and reason both the selfish and the not so selfish want the same things. Comity, Peace and Security on the land.
