Free markets are and always have been the tool of the powerful to bludgeon the weak.
How much did India and China benefit from Britain's advocacy of free markets in the with century?
How much did the working poor of any nation in that period?
Or this period, for that matter?
Free markets are a tool of the rich and powerful to keep themselves so, and to make themselves more so. Which is why the richest, what, 1%? Control half of global wealth.
Free trade is not always fair trade. In the free market, fair trade values must be upheld, so there is a meeting point between seller rights and buyer rights. The role of the government (as a supervisory authority) must be emphasized so that a free and fair market system that is free of manipulation and monopoly can run optimally. That way, a fair business system can be created, of course, the government must be fair by being neutral and subject to existing values and rules. The rules must overshadow justice, the rights and interests of all people. Because the allocation and distribution of resources is fair and efficient, they cannot automatically be realized by themselves based on market forces
The absolute free market embraced by liberals and capitalists is the wrong concept of a free market. Freedom is always followed by accountability (humans must be responsible for all their behavior because they have freedom of choice) a simple example of people knowing that illegal logging will cause the effects of floods and landslides. Disposing of waste into rivers whose water is needed by the community to wash and bathe is a wrong thing, but because they want to get the most profit, the values are set aside or forgotten.
Some things that need to be monitored by the government are freedom of market entry, promotion and propaganda arrangements, the prohibition of hoarding goods, regulating trade intermediaries, and price control.
