In developed countries almost all the infrastructures had already been put in place thus facilitates smooth running of the economy whereas in developing countries all these are in non existence or rather are being built thus it invariably leads to poor growth of the economy and economy activities will be at the lowest ebb.
The big difference in developed and developing countries is this that the people of developing countries cannot rise for their rights because the government will push them back and the ruling party acts like kings and assumes that this country is their own property and they will do what they want to do. People receive no basic facilities of life and lives in worst conditions.
