Native Americans as separate tribes of people were here before us but they were also immigrants at one time. None of the original native Americans are still alive. Some of us have families that have lived in America for 100's of years. Being born here makes us native Americans. Everyone can't live on a small family plot for thousands of years people grow and move. The illegal immigrants want to move here and have children for the very reason to be a "native" American with all our rights.
Our taxes are used to pay for more room in prisons, more care in hospitals, more education. This is theft taken from our taxes.
Legal immigration has been practiced for hundreds of years. It is a slap in the face of honest immigrants who "undergo an extremely complicated process" become an American to let the illegal lying and deceptive immigrants. A socity isn't made better by letting lairs, deceivers, thieves and the like overrun a country. Who cares if right and the left appreciate illegal immigrants because they can employ them for below minimum wage. Illegal is still illegal. Wrong should never be rewarded.
America is also the biggest refugee intake in the world.
