Not exactly. I think you mean the people in Capitalist societies, who complain the most about Capitalism, are the people who depend on all of the Socialist rationing that exists in Capitalist societies. Since they are dependent on Socialist rations, they hate the Capitalists. Because, in their minds, the more the Government takes from those who depend on Free Economics, they believe, the Government will give them more. It rarely ever does. If they just left the Socialist Government dependence and entered into the Free Economy, they’d quickly get more. But to do this requires abandoning their addiction to Socialist dependence.
We all know that it is nearly impossible to cure longstanding addictions of any kind. From smoking, to gambling, to drugs, to anorexia, to overeating. The same is true for addiction to Socialist rations. Like all addicts, the Socialist rations addicts are sick and miserable.
