Thanks so much @cheovarnez :-) I'm not Spanish or Portuguese, so my response is based on the Google translation of your comment...

I agree with what you're saying here; all major transitions, especially the political and economical kind, have to be done with the greatest of care to not repeat the mistakes of the system we're trying to leave behind us. However, communism strives for a society without state or money, which seems Utopian, but isn't anywhere near the totalitarian forms of the state socialism and state capitalism horrors of our past.
