Many countries around the world do not have the resources or leadership to support growing populations. Changes in the environment both natural and man made reduces the population’s ability to support themselves. The quality of life goes down and the people get word such as other places where living is better. The United States with all its social programs makes it better for this over population to live. The United states has a finite amount or resources also. Much of the social programs do not have the resources so they put the federal Government into debt and a promise to pay back with future growth. This is a ponzie scam and leads to inflation and reduced quality of life for working Americans. Many American citizens find that they do not have to work to survive and cause a drain on those that do work. This is not sustainable.
