"Why Won’t The Nightmare Dream Of Communism Die?"

"A century of Communism achieved four main results: poverty, oppression, war, and mass death. So why does anybody still think collectivism is 'idealistic'?"

Glenn Reynolds has, I think, the right answer: "For the same reason Ponzi schemes won't stop. It's an effective con that zeroes in on human weaknesses. Ponzi schemes capitalize on greed. Communism capitalizes on envy, which is why it’s largely sustained by intellectuals, in whose personalities envy tends to be a particularly powerful component."

Two different but complementary views on "trickle down economics"

"The Trumped Up 'Trickle Down' Economics Myth".

The idea of “trickle-down theory” is nonexistent, except as perpetuated by those opposed to across-the-board tax rate cuts that include the wealthy. 

"Sorry Envious Left, 'Trickle-Down' Economics Is Real, And It's Everywhere".

And while anecdote should never be confused with fact, the story of Coca-Cola helps disprove the emotional arguments against trickle down.  With Coke we see how an immigrant rose to near billionaire status in concert with voluminous job creation, staggering amounts of educational and charitable opportunity, and even more giving by the inheritors of great wealth.

"Labor’s Share of GDP: Wrong Answers to a Wrong Question"

Alan Reynolds:

When people say “labor’s share is falling,” they surely mean income people receive from work has not kept up with income people (often the same people) receive from property: dividends, interest, and rent. But, that crude Piketty-Marx labor/capital dichotomy ignores another increasingly important source of personal income: namely, government transfer payments from taxpayers to those entitled to cash and in-kind benefits.  

"Funniest retraction I've ever seen"

I agree that it is pretty funny.

The American Journal of Political Science published a correction this year saying that the 2012 paper has “an error” — and that liberal political beliefs, not conservative ones, are actually linked to psychoticism.

“The interpretation of the coding of the political attitude items in the descriptive and preliminary analyses portion of the manuscript was exactly reversed,” the journal said in the startling correction.
