But please. Think about the number of immigrant people that are too many for any given situation to remain reasonably stable. And then think about the 3 billion people in this world that would give everything to be a migrant worker in your country. Why don't we accept them all? Why don't we invite everyone, from everywhere. Stricly everyone. No limits, no questions asked, everyone's invited, the more the merrier.
Why not? We let some in, why do we treat them different.
Think of oodles of people, marching without end, a never ending stream of human flesh, a quarter mile wide, endless over the horizon. A Tokio subway in rush hour. Without end. One person per square foot, for as long as the eye can see.
Is that too many? Is it racist even though the immigrant's "race" is absolutely irrelevant here?
Is there any number of people that are too many, any number after which migrant workers become invaders?
If yes, we need to get honest and discuss on which number that is.
If no, we need to be consistent and let everyone in, all 3 billions. Everyone living in a household with more than 3 square foot per person should freely accept another migrant worker into their apartment. And then another one and another one, and then some more. And their children. Don't be racist, let them in until every inch of floor is covered with people.
