It's a simple biological fact. Both moral character and intelligence are strongly inheritable. Countries stop working properly once the average IQ starts to drop below 100. Any society in which people with IQ's below 100 have more kids than the people above 100 is doomed to fail. Jews accelerate the process, but I guess the root cause is more the Christian morality, which is almost entirely dysgenic ... but you can educate me about how you are going to change this reproduction pattern by removing the Jews.
