Michael Sandel 3:Why we shouldn't trust markets with our civic life
Summary
This is the problem like happening in Japan right now and I've just read a similar article. In Japan, there is unconscious discrimination. It is because Japanese people don't have backgrounds living and talking with different races. Japanese society hasn't accepted in immigrants and even refugees. Japanese government thinks that the main of markets is an economy and it is not important how people live if the economy grows better. However, it loses a lot of important things.
The speaker tells us that our market has been changed to market societies from a market economy. A market economy is a tool, a valuable and effective tool, for organizing productive activities, but market societies is a place where almost everything is up for sale. It is every aspect of life which includes personal relations, social practices, family life, health, education, politics, and law.
Economists assume that markets don't touch or taint the goods when they exchange them. It means not to change the meaning and the value of the goods for exchange though it can't use for our market society. It is because our market society includes personal relations, education, and other important meanings, and they shouldn't be changed by money or exchanging them with money.
It creates inequality but it makes us worry without realizing.
Thus we shouldn't trust markets.
There should be certain moral and civic goods that markets do not honor and money cannot buy for our place where people of different social backgrounds and different walks of life can encounter one another ordinarily.
It teaches us to overcome our differences and to live happily.
