But people soon realize that this way of exchange is still cumbersome. Since the function of money is to measure or represent the amount of labor involved in producing the product, a piece of paper can do the same job and is much easier to carry and use. Thus, money changes form from a material good to a bill. People then discovered that even the bill is not necessary. Since the values are expressed in numbers, the exchange can be done numerically without a piece of paper. Thus, money changes form again from the bill to the digital figure on a bank card. This digital figure now becomes the life ambition of the modern people. Euphemistically, that is called "the pursuit of happiness."
Such practices undermined the fundamental principle in trade. The essence of trade is the exchange of labor. A fair exchange reflects the equivalent amounts of labor involved in producing the products. Since the exchange rates of all products are proportional, the increase in price of one product will trigger a chain reaction of inflation. As a result, houses, cars, food, groceries, clothes, utilities, services, all become more expensive, and the government has to raise taxes just to keep even if nothing else. The victims are the ordinary people. In today's America, 63% of people are unable to pay a $500 surprise bill, but a small number of people benefiting from the unfair practice and the system that they have created have accumulated tremendous wealth that reached astronomical figures.
Greed knows no limit and most crimes of our times, caught or not caught, are motivated by money. In a mammonish society, science, education and medicine all become the means of making money, and money respects no morality. The winners are those who have found ingenious ways to abuse others, and the losers are the ripped-offs. As a result, people lost faith in goodness, honesty, fairness and trust. A man once could feed the whole family, not anymore because the prices become so outrageous that women also have to work in order to maintain the middle class standard of living. Feminists may call it "women's rights" and "equal opportunities". In fact, it is the enslavement of women. A woman lamented, "More and more women work extremely hard to make money now. The society provides women with less and less security. Security used to mean a commitment, a clasped hand when crossing the street, now it is the money in our pocket and a fully charged cell phone... We all want to marry a man, only to find ourselves turned into men!"
