Socialism has been the "wave of the future" for enough of the past now to offer a fairly clear conclusion that it will always succeed in the future and never in the present. The only thing that socialism succeeds brilliantly in producing in abundance is excuses.
Its acolytes are nothing if not stubborn, though. Prior to "let them come to Venezuela" was "let them come to Cuba" and we saw a steady stream of starry-eyed left-wingers get a Potemkin Village tour of what Castro wanted them to see and declare a workers' paradise: 100% literacy, 100% modern medical care, prosperity and brotherhood for all, when the reality was perfectly visible and the illusion nearly impossible to maintain without shutting their eyes and stopping their ears. Michael Moore, anyone? This has not changed with the opening of tourism to that miserable island except that the stream of eager True Believers has dwindled to a trickle. The two-tiered economy and exploitative tourism that so oppressed Cuba under Batista is now...well, it's actually back. And it happened under socialism.
So don't expect very many Millennials or anyone else without a solid ground in history to ignore the fantasy-world promises and embrace the society that has made them wealthy beyond the dreams of any medieval king. The Left has succeeded in changing the standards to perfection for present society and no standards at all for the ones they've screwed up in the past. Those, we are told, need to be denied, marginalized, or excused, "debunked", reconsidered, or simply ignored, which is precisely what they intend to do with the mistakes of the present. What a pity you can't eat dreams and noble slogans.
Socialism has been the “wave of the future”
It sure was for the 190 million socialism murdered during the 20th Century ...
