I would rather illiterate let Africans immigrate to my country than the same number of educated Israelis
Unless they denounce Judaism and all it's racist ways
An educated criminal is more dangeous and has more sway over public policy
An uneducated criminal would simply be imprisoned or executed after their first crime as long as there are no educated criminals to protect their crime spree
Educated crininals indirectly murder more people because they do so through policy without penalty
That's an interesting thought experiment.
The way you've stated the hypothetical, I 100% agree with your conclusions.
An uneducated, undirected, easily-lead class of immigrants can be quite useful with proper management.
The opposite can be literally devastating.
The other scenario you didn't mention relates to Islam: a largely uneducated, less intelligent, but very directed and not easily-led class of immigrant.
That poses serious problems too. This is why Jews have made Islam their eternal foe.
If Muslims ruled the world everyone regardless of ancestry could convert to Islam to avoid punishments for being a non muslim
If "Jews" ruled the world they would discriminate against people who have the wrong ancestry and who have not converted and make conversion difficult or impossible for people of the wrong ancestry
People without Jewish ancestry certification are better off in a world run by Muslims than run by Jews
The facts of Judaic and Islamic law agree with your conclusion.
The historical evidence of actual mixed Islamic/Judaic societies also supports your conclusions (Ottoman Empire = Jews live, vs modern day Israel = Muslims get rekt).
BUT. you don't include Christianity (2.3 billion people), or Hindus, Buddhists, atheistic Chinese/Japanese/Koreans.
The world is more than Jews and Muslims.
Confucianism as practiced in modern variation in China, North and South Korea, and Japan = Blind Authority Following
Is very dangerous but is not really a religion by itself in isolation, it combines with other religions then has people blindly follow authority figures of the religion it combined with
Atheism is really State-theism in most cases
Rare exceptions like Molyneux who claim to be Atheists but do not believe in government end up very similar to Christianity minus God
Sure, get some rest!
