Economics is the study of human decision making. It doesn't change with the times.
You keep making up stuff I never said. Why is that? 
No, that is the study of philosophy, psychology, and sociology.
Economics is the study of money flow and distribution.
That might be half your problem, you have the wrong understanding of what economics really means. Econimics is fundamental and always comes down to the money sign. If you allocate money one direction for a certain amount of time you can record the changes it makes over time. Econimics flows in a chain reaction, if economies are overvalued they get corrected because people cannot afford products and prices must drop, if economies are undervalued, either you have to increase the money distribution to other areas or you have to make monitary sacrifices to adjust in order to gain prosperity in the long run. If you cannot do that, the economy will fail.
China is cheap, has low standards and is undervalued, they built their economy by stealing our production and workfroce for cheap. That in turn increases the value of their economy becsuse more money is being allocated to their markets. This causes the other market to lose value now because the money that was flowing inside that market has now shifted toward an outside economy. If you take money out of one economy and put it in another, you allocate the money out of the original market flow.
Greece failed because they do not have a proper money flow. They could not steal labor and productivity from the markets so they had to take out loans in order to fix their money flow. Their businesses dont make enough money, are taxed too high, and tax allocation is not directed properly, therefore they fail.
Business owners in America make up a very small portion of the population but do make over 400% more than the average middle class worker. If those business owners don't allocate the money correctly and intern reap higher % every year, instead of giving a % back in raises, than how do we expect to grow as a healthy nation? How do those businesses expect peolple to buy their products if they have to raise prices? 15 people with all the money doesn't make society a better place, they don't have the spending power that 250,000,000 other Americans have. This is why some nations are very wealthy while their people are poor as hell. The Government takes their money in taxes and gives nothing back. If you allocate the money better to 250M people, they will have more to spend and more to own, thus making the zone economy prosperable. The only way to do this is to pay Americans more and bring back the working class industry to America. These are sacrifices American business owners have to make if we want to see a happier and more prosperous society.
