That’s an ethical question and not an economic question. We can focus on the economic side of capitalism and communism.
No. In a free market the consumer has the power of who fails and who doesn’t fail (profit/loss). The current western democracies are not capitalism as they are political systems that initiate physical aggression upon the free market and redistribute the wealth gained in the economy. These are two distinct entities where a governmental system exists. One is free market were all the workers are out trying to make a buck to just get by. Whereas the political system preys upon the hard work of people and redistributes the wealth. It is destructive to have coercion upon the free market. It destroys wealth and the poor people are usually the people that are effected first by government policies. The special interest groups that go to the gov’t for legislation and handouts stifle competition and therefore the price system is distorted by all the socialistic measures that have been taken, ie. social security, minimum wage (which creates unemployment), all the other gov’t laws that come out of the Dept. of Labor, Environmental Protection Agency, etc… The price system is key because it creates malinvestments in supply and demand. As gov’ts distort the market with interest rates, monetary policies, etc… thereby devaluing the purchasing power of the dollar (for instance), then as more wealth or regulations are redistributed around in the economy it is NOT clear what the consumer is demanding. If that is not seen, then it creates unemployment and poverty.
In a free market businesses have to make the effort to NOT be greedy because if consumers don’t like their product then the businesses go bankrupt. Businesses therefore have to give, not be greedy, they have to give what consumers want or else the business fails.
Liberty doesn’t undermine morals. Liberty semantically means absence of initiated physical aggression, ie. peace. So liberty can’t be immoral or undermine morals. It is violence and coercion that undermines morals.
Money is simply a medium of exchange. It is how complex economic systems above barter work. It is how I can go to the store and get a lamp from the lamp owner when I don’t have anything the lamp owner wants to barter (outside of currency). Yet the lamp owner will take the currency I have because he/she can use that currency to buy what he/she wants that I didn’t have to offer other than the currency. It makes exchange in higher order good system, ie. capitalism work. Money is like any other economic good in society. Money is the same as a watch, door, TV, food, etc… It is valued so much though that people will trade money more than in the market than all other economic goods.
