Cause and Effect.

Considering that the economy is changing so fast in the United States, teenagers graduating from high school are getting prepare to decide what way should they take to confront their future. Should they go to college? Or should they start working right now? The thing is that the change of the manufacturing economy to service is one of the principal effects of the United States job market in the last 100 years ago. And if these teenagers want to have a good job that pay well, the best way they should take is go to college; because of 25 excellent service jobs in the United States at least 18 require a bachelor’s degree.
One of the principal effects of the job market change in the last 100 years is the change from a manufacturing economy to a service economy. A lot of reasons explain this change in the U.S economy. First of all, the numbers of manufactory jobs has decreased significantly because two basic causes; the automation replacing factory workers and the manufactory is now done outside of the U.S. For example, the percentage of manufacturing jobs has gone down dramatically since the beginning of the 20th century and it will continue to decrease in the 21st century. But on the other hand, the number of service jobs has increase a lot, again because two reasons, one is the change of the American population and the other is the technology. At the same time that the manufacturing jobs has gone down, there has been a great increase in percentage of service jobs. Basically 100 year ago the, only 20% of workers worked in service, but today 80% do. And we can see too that by the 2020, the percentage will increase to 90%; in other words the workers in U.S will supply services and not products. Well other important effect of the changing job marked in the Unites States, and one of the most important around the world capitalized is the development of new technologies applied to the industry, the economy and the urbanization of most of the countries, I mean, the automation of the factories, the technician of the agro industries, the use of the microchip in almost all the appliances and the majority of the tools in the emprises. All of this have changed the modality of working now day, as example, in a factory, the factory needs personnel staff that must be qualified to work with machines, therefore if you expect to work in a factory you should start your training, other simple example is that the people who work now day in a job with a good salary have to know how to use an computer, I mean, that if you want to join of the culturing of consumerism, you have to know how to go with the hand with the technology.
