How and why have highly developed nations deindustrialized?

1. A consistent decline in employment in manufacturing, due to social conditions that make such activity impossible (states of war or environmental upheaval). Manufacturing requires access to natural resources and raw materials, without which production would be impossible. At the same time, the rise of industrial activity has done great harm to the very natural resources on which industry depends. In China, for example, industrial activity is responsible for record levels of water depletion and pollution, and in 2014 more than a quarter of the country's key rivers were deemed "unfit for human contact." The consequences of this environmental degradation are making it more difficult for China to sustain its industrial output. The same is happening in other parts of the world where pollution is on the rise.

2. A shift from manufacturing to service sectors of the economy. As countries develop, manufacturing often declines as production is shifted to trading partners where the costs of labor are lower. This is what happened to the garment industry in the United States. According to a 2016 report by the Bureau of Labor Statistics, apparel experienced the "largest decrease among all manufacturing industries with a decrease of 85 percent [over the last 25 years]." Americans are still buying as many clothes as ever, but most apparel companies have moved production overseas. The result is a relative shift in employment from the manufacturing sector to the service sector.

3.A trade deficit whose effects preclude investment in manufacturing. When a country purchases more goods than it sells, it experiences a trade imbalance, which can reduce the resources needed to support domestic manufacturing and other production. In most cases, the trade deficit must become severe before it begins to have a negative effect on manufacturing.

b because it can only be win one time and lose at one time

explanation:

there are chances on rare cases

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
