The only antidote to this nonsense is to point out how suppressing the free market is what hurts people. Crony capitalism is what hurts people.
The dismal record of socialism is a matter of record and the fruits of socialism (which leads to communism) are easily pointed out.
Problem is these people have to listen. And think. A tall order for a lefty.
Adam Smith, (remember him? "Wealth of Nations") said about 250 years ago that:
People of the same trade seldom meet together, even for merriment and diversion, but the conversation ends in a conspiracy against the public, or in some contrivance to raise prices.
When they use their clout to affect government policy, there you have "Crony Capitalism."
But as far as your suggestion being an "antidote", I will point out one obvious flaw in it. The public has become stupid, and you might as well be talking to pigeons for all the good it will do in attempting to inform the public regarding what is to them, a very abstract concept.
Put the idea into a simple cartoon that is both interesting and entertaining, and you might get somewhere with it.
I was talking to a lib the other day about Zero and she told me that she really liked what he had done for her healthcare, it now costs her family of 4 nothing. I explained to her that only meant other people were now paying her bill. Needless to say I did manage to piss her off. I figure it was a day well spent.
