Healthy capitalism means healthy free market in which all transactions are genuinely free. By free, it means that the will of both the seller and the purchaser in any trade is fully respected. Once monopoly appears, such respect gradually disappears; free market is gradually losing its true free nature, free trade is eroded.
One big misfortune and misconception in today's society is that, when people talk about monopoly, they only pay attention to capital monopoly, but completely ignore the monopoly of labor force. Not only that, they even encourage and promote monopoly of labor force by law, glamorize such monopoly in every way, in morality, in public opinion.
Labor force monopolization is far more dangerous to the human future than monopolization of capital. Capitalism is dying under our nose; the main culprit is labor force monopolization.
If America wants to survive like what she was (not "is"), she must apply anti-trust law to labor force monopolization with ten times of strength as what she has done to the capital monopolization. Otherwise, all of us must prepare to live in a Socialist America very soon.
Socialism, a social system that condemns and subsequently expels free market, must be a system that embraces forced trade. She has no other choice. Can you think of other form of trade besides free trade and forced trade? Forced trade means one hundred percent of enslaving. Do you see other choice?
