Read my post, it's pretty clear. Unless you are 100% Native American you are a descendant of immigrants. Again, this country was built on the backs of immigrants, this "American system" you claim immigrants are taking advantage of only exists because of immigrants like your forefathers.
Not that I wish to get involved but even Native Americans immigrated to this land and descended from nomadic tribes that probably originated in Africa, before moving east across India and Asia before completing the trek across what we now referrer to as Alaska and down the west coast beyond baja and finally down to the South American Peninsula.
So unless you are the Eschscholzia Californica flower, you immigrated here.
