Since most of the people being disappeared by ICE are in the system they are legal immigrants.
If we are honest about immigration we will admit we are not doing what needs to be done . We would have signs in Mexico directing immigration to ports of entry. We would have Ellis island type centers to receive people and record refugees or asylum status. But all we did was let people be on their own in an unknown way. They did ask for status as best they understood our rules.
Beyond that if we truly want continued growth we need more people. Being bigots and making it hard will never build a good America.
Growth is not the goal. Not if the cost is loss of social capital and cohesion.
