In contrast to Senate Amnesty and Guest Worker and continued legal immigration, Tom Tancredo proposed a pause in legal immigration in the Republican presidential debate.
Against a pause:
Huckabee against pause.
Rudi Giuliani against pause. Compared Tom Tancredo to Know Nothing party. Backward looking logic. Giuliani advocated perpetual immigration. (This was proven mathematically to cause genetic extinction of those who come here and those who are here at any point in time. See Immigration Vanishing Survival Theorem
McCain No barriers and fences.
Repost in part on Unpleasant Immigration Arithmetic:
Assume US population at 300 million was the maximum. If people live 75 years, then 4 million die per year. If 2 million enter then births = 4million deaths – 2 million entrants = 2 million.
The ratio of births to deaths is 2/4 or 1/2. The time from birth to parent is roughly 25 years. So in 50 years, one has 1/4, and in 75 years 1/8 of the starting genes.
Even if population went to 450 million, deaths per year are 6 million. With even one million entrants that gives a survival ratio of 5/6. So the number left after 25*n years is (5/6)^n which goes to zero as n goes to infinity.
It goes to zero rapidly in fact.
The above implies that any law with immigration above zero on a sustained basis is unconstitutional and a crime against humanity. Causing the extinction of a group is a violation of treaties the US has passed.
The current US law is thus void. So is the proposed law.
The drop in fertility from 1800 to 1990 in one graph shows this substitution effect pressure from immigration.
Look at the Karen Stevenson graph of fertility from 1800 to 1990 below:
Fertility falls except during the period of immigration restriction from the 1920’s to 1965. During part of that period fertility rose, which is called the baby boom. This was a departure from the uniform fall in fertility.
Fertility is now below replacement for many groups in accordance with the theorem. Sustained immigration is omnia cleansing.
The same applies in Europe where fertility is below replacement.
We must stop immigration, we must stop legal immigration and we must stop illegal immigration. We can not have any amnesty or legalization. We have to get the rate of illegal immigration to zero, not just slow it down. We must get the rate of legal immigration to zero. The theorem requires this until the world changes so much that two way equal migration is viable. But that won’t be viable for centuries.
