Assuming that what you really mean is to limit the right to own businesses to those who can prove ancestry of 5 generations of US citizens, you would be denying business ownership to 4 generations of Native born Americans (about a century's worth). That's not the dumbest idea ever floated here, but it's close. ----- jim o\-S
