Sum, you're talking ideas, not facts. You're merely reasoning from A to B, without confirming B with empirical observations.
In fact, Sum, your honest capitalists are often screwing each other over -- this is why the courts are filled with lawsuits. Again, your compassionate capitalists are often dumping toxic wastes into other people's backyards. Witness most recently, fracking.
And I could go down the list countering each of your points with examples from the real world. Your view of capitalism only holds up in fantasy romances like those written by Ayn Rand.
I read his post a little differently. It seemed to me that he was speaking of the ideal capitalist system.
His post didn't suggest to me that he's out of touch with reality. I share his views. An ideal capitalist system would work this way.
Regardless of the flaws within capitalism, it would be dishonest to claim that there lacks fairness, opportunity and compassion.
If we were to approach this honestly, for many identified negatives - we could find a positive for comparison.
As one company ruthlessly destroys the environment - another pushes for green and clean.
As one company mistreats its employees - another invests in employee development and offers competitive benefits.
For those that cheat the system - there are others that play fair and because they want to.
For those that refuse to plant seeds in their communities -there are others who contribute generously thru various philanthropic/charitable avenues.
Do the negatives, realistically outweigh positives? Perhaps - in measurable and immeasurable ways. I do not believe alternatives to be without flaw and their own brand of unfairness and corruption.
