The premise of this article is incorrect from the very start.
You cant argue effectiveness or ineffectiveness when it comes to socialism. No one backing socialism is the least bit concerned about whether it works as a governing system. And people will not vote for socialism because they think their lives will be better because of it.
Socialism is implemented by its adherents in order to create a form of dictatorship wherein they will be part of the elite. A permanent system with them at or never-enough the top.
People - the voters - will vote for socialism as a means of sticking it to someone they think is better off than they are for whatever reason...stick it to the white man and trample him down, let him get the bad end of the stick like Ive had all my life...stick it to the rich, the corporations, the religious, the man, the straight people - whoever and whatever you hate in life. Its just a new word put on the old idea of tribalism. Us vs. Them, the perceived Have Nots vs. The Haves, over-turning the culture. Its all just emotion.
So arguing the logic of socialisms built-in failure is besides the point. Its really all about returning to a form of dictatorship by using an underclass to overturn a culture and exact revenge on those perceived as successful in the prior system. Its all emotion and no thought outside of conquest.
BINGO
