A national identification number or National Identity/Insurance Card number is used by the governments of many countries as a means of tracking their citizens, permanent residents, and temporary residents for the purposes of work, taxation, government benefits, health care, and other governmentally-related functions. Sometimes, the number will appear on an identity card issued by a country. In the United States we have a social security number, however there is no centralized system that links it to everything else like a National Identity Number would. I personally think it would be good, especially for limiting illegal aliens who are a drain on resources. As part of the social contract the government needs to know that the people it is providing services for are actually citizens. A National ID could help centralize this sort of information. For example in order to register at a public highschool or get instate tuition in college a person could be required to present their national ID, same with getting treated at a hospital, or even obtaining a driving licence. What do people think about United States adopting such a system? Do people in other countries find it to be successful or limiting? What do other Americans think?
