What is your opinion about Communism?

[Anomalocaris]

This is why those opposing capitalism often discover too late that there are far too many traitors in their midst for them to succeed.

Are there not too many "traitors" in our midst for capitalism to succeed, as well?  They certainly seem to be present in capitalism's greatest failures.  Doesn't that strike you as a shared weakness?  Whether the means are held publicly or privately, bad actors are a problem.  This is also discovered late in capitalist models....like when the pipeline bursts, or the bank goes bust, or the bullets are fired.  When the losses are socialized, after the privatization of profit.

No. The problem isn’t capitalism doesn’t fail or fail spectacularly, nor that it contains no glaring inequities.   It is that, on the whole, capitalism seem to be able to offset its failures and inequities with enough persuasive successes such that when it is put before stakeholders in both capitalistic system and any alternatives that have been tried on a large scale, capitalism seem to gain more converts than its competitors on the strength of its track record of successes, despite it numerous failings.

For all of capitalism’s failures in the developed world in the last 25 years or so that put perhaps 100 million of the 600 million denizens of the wealthy economies of the first world in moderate danger of a moderate reduction in their first world standards of living, during that very same period capitalism lifted well over 600 million people in just China and India alone from abject subsistence poverty to an infinitely higher, modern standard of living for the first time with cars, modern housing, foreign vacations, and leisure time and discretionary purchasing power approaching those of the first world countries.

100 million first worlders facing reduced economic security, vs 600 million third world former subsistence farmers now within a stone’s throw of first world standards of living. I don’t think capitalism need worry over much about being undermined by more traitors in its own midst than amongst the ranks of its competitors.
