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.
Normally, development is totally based on the economy of the country and the value of the economy, the standard of living of people and how well they are taken care of with all the amenities provided for them to live a good life. Simply, this is not something anyone can see in an underdeveloped country and that is what differentiates them.
Usually, if there is infrastructure, businesses will thrive better, there will be more organizations popping up, unemployment rate will reduce and things would get better.
