Why don’t we take the time and resources into enforcing and instead put it into resources to make these people legal citizens. We are the land of the free and the land of dreams. People come here to better our country and to have a better life. So let’s use the resources to allow them to obtain those dreams. Make them taxpayers and citizens and our economy will boom. It would cost more to arrest them to help them become tax payers. It becomes a sustainable system.
