Lets get discuss about the differences between the developed nation and the developing nation.
First of all employment is the thing which makes the countries stand out from each other in well developed nation there will be enough employment option will be made by their government according to the population on their country which can increase the better standard of living in that countries but the developing nations are struggling to find the job opportunities for their people.
If a country will provide enough opportunity for employment for every individual, I can say that country is a developed country. As the economy of the country developed, better social protection service also being developed.
I think the main difference of developed countries such as China, USA, South Korea and Japan to Developing countries such as Philippines, Thailand, Vietnam and many more is the capability of the countries to manufacture products and import it to all countries worldwide. Most of developed countries right now is a Producer countries importing products all of the world. While the developing countries is much more of a consumer countries. As you can see developed countries is the trendsetter and the pioneer in Science and Advanced technology.
