In the modern world, the power of market seems to be excessive. Well-being is usually measured in one’s purchasing power, and the range of goods and services for sale has greatly increased. However, there must be some moral line which separates trade in commodities from values which are beyond money.
The division between what can be sold and what is essential to keep is to some extent subjective. Every person draws their limits of markets themselves. Some people may think that they can sell sex but they cannot sell love. The others may be perfectly sure that they can sell own organs but they cannot exchange their children for any amount of money. People in need, for example, may treat any possession as something which is worth money as they need it so badly. On the other side, there are people who have money and wish to use it to buy love, power, or respect of others.
Perhaps, philosophers have a point when they state that unlimited buying and selling enhances inequality and corruption. Trading objects and services which can be given for free, wealthy individuals deprive poor people of the ability to get things like healthcare, education, or recreation for free. As soon as the society which underwent commercialization faces the evidence that things of a certain kind are for sale, they will not lose their chance to make money on them. For example, if human organs were legally for sale, will someone donate them?
Moral limit of markets depends not only on social class and lifestyle but on basic ethics which we have learned as children. If people put more value in money than in human virtues, it probably indicates that they have grown in the troubled social environment.
