Megan McArdle discusses the failure of communism beyond the small scale . . .

. . . but misses that its origin is in the most intimate unit of small scale experience of all, the nuclear family. Once you extrapolate much beyond that level ("Here are my mother and my brothers! Whoever does the will of God is my brother, and sister, and mother." -- Mark 3:34f.) it's not going to last long.

Megan McArdle, here:

[C]ommunism has never successfully worked above the level of a small group; it’s trying to manage transactions with strangers on the logic of small-group reciprocal altruism. Those small groups have a lot of social mechanisms, from shaming to threat of exile, to prevent people from cheating. When you try to scale it up to millions of strangers, it collapses into destitution or bloody tyranny. 

And all that believed were together, and had all things common. ... And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own; but they had all things common. ... And one of them named Ag'abus stood up and foretold by the Spirit that there would be a great famine over all the world; and this took place* in the days of Claudius. And the disciples determined, every one according to his ability, to send relief to the brethren who lived in Judea; and they did so, sending it to the elders by the hand of Barnabas and Saul. 

-- Acts 2:44; 4:32; 11:28ff.

Save Your Selves From The Libertarians: They Think You Are Worth Less Over Time

As Megan McArdle thinks, formerly of The Atlantic, here:

Human capital is like almost any other form of capital: it is a depreciating asset.  The longer you stay out of the workforce, the less valuable you are to potential employers.  You lose market intelligence and industry connections.  Your technical knowledge and skills atrophy.  And as my colleague Don Peck wrote in a devastating piece last year, the psychological effects of long-term unemployment change you permanently.  Many of the people who have now been unemployed for years may never work again, or not at anything like the income that they had been expecting. ... Now think about what is happening to millions of people out there ... whose savings and social networks are exhausted (or were never very big to begin with), who are in their fifties and not young enough to retire, but very hard to place with an employer who will pay them as much as they were worth to their old firm. Think of the people who can't support their children, or themselves.  Think of their despair. That is what these numbers mean: millions of people, staring into the abyss of an empty future.  We don't know how to re-employ them.  The last time this happened, in the Great Depression, World War II eventually came along and soaked up everyone in the labor force who could breathe and carry a toolbag.  I hope to God we're not going to do that again, so what are we going to do with all these people?

That's what objectivism does to people. It turns them from your brother into The Other. But in your heart you know it is not so. You'll only be an object if you let them make you one, but to G-d you'll always be a subject, in which He is deeply interested.

Behold the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they?

-- Matthew 6:26

Jesus, or Megan McArdle?

Jesus (Matthew 6:25):

"Is not life more than food, and the body more than clothing?"

Megan McArdle (here):

"Human capital is like almost any other form of capital: it is a depreciating asset."
