Whenever anyone says anything bad about the free market, it is generally a misplaced critique of government. Whenever someone says something good about the government, it is usually a misdirected praise of the free market.
For example, democracy is often praised as a way for people to get what they want. Yet, by definition, those who are not in the majority do not get what they want. Even those in the majority often do not get everything they want, but merely their preference between two unsavory options.
In contrast, the market gives everyone exactly what they want. You don’t have to choose between a pickle flavored yogurt and sauerkraut bubble gum. You can choose not to buy either.
A common objection to freedom is that if everyone were allowed to buy and sell whatever they wanted, one person could buy all of the water, and then everyone would be at that person’s mercy. It is truly a horrifying thought, that someone might have that much power over you.
