Immigration filters out everyone but the very elite. The most greedy overeducated and privileged get into Canada. We are literally asking our kids with an IQ's of 100 to compete against a flood of asians with IQ's of 140. The foreigners that slip into Canada are not a normal population.
We need only look at who is making it into university. I urge all parents to visit the local university to see what I mean. You will only see foreign kids. This is no exaggeration.
Terrorism is not the only threat posed by these unwelcome foreigners. Just go to a hospital. We need to find an explanation why all our doctors are foreigners. Why are all the good jobs going to foreigners. Foreigners like to imply that our kids are lazy. I have never seen this. Our kids are just as hardworking. The problem is that the population of foreigner in Canada is very unnatural. Economists agree that the mbutt immigration of elite foreigners in the past 30 yrs has put millions of Canadians out of work. This is just fact.
The main problem is that many older Canadians are racists and simply underestimate the threat posed by non-whites. It seem ridiculous but many canadians think that a brown PhD is not a real PhD and that our kids with a grade 12 education can compete against that. We are facing a second Pearle Harbour.
