Over the last 5 decades the Mexican government has been sending it's less desirable types (often genetically less Spanish) up into the US and Canada. A huge chunk of these immigrants are living here in legal limbo. Which causes a lot of problems. Local governments are forced (out of guilt created by Jew media) into educating their children. Homes are gobbled up and squatted on by multiple families. Voting ID requirements become harder to pass because it would disenfranchise all the illegals that might want to vote. Only sales taxes get paid. Citizens in legal limbo are afraid to interact with police and report crimes.

To make matters worse Mexico even allow immigrants from other south american countries to pass through mexico and into the US. Guatemala is one such country that does this. So the US doesn't just get Mexican cast offs it becomes the home of anyone in south american or anyone who can get to south american.

28% of Mexicans have light eyes and 18% have blonde hair...

It even goes to state that 47% of Mexicans have light skin.

I'm not sure why this surprises you. There was a caste system in south america even before the US was a nation. Additionally there are quite a few Germans and White American expats (such as Mormons) that live in Mexico. Most of the beer you drink in Mexico is German made.

The problem with mexico is what I mentioned earlier. They use the United states as a relief valve. They also send un taxed remittance payments out to the tune of billions. This starves the US of tax dollars causing working Americans to get taxed more. Another big issue is that the government is 100% Rothschild banking family controlled. There's a reason why the government always seems to fail at getting rid of cartels and that's because the cartels are controlled by the Rothschild international banking as well. Human trafficking is big business and the cartels are tied up in it big time. It gets complicated though because much of the populace of Mexico prefers the cartels to the Government. They can see the corruption and don't like it. We use to have a DAR poster that lived in Mexico and would drop info about the politics there and the border runs before they happened.

Mexico is pretty dysfunctional and has always been seen as a mestizo country by everyone

Agreed but the Jews have been wildly successful communicating to Mexicans that there's no such think as race. Mexico, like Brazil, is a big genetic melting pot full of degeneracy. I found it hilarious when the conservatives tried to claim Mexicans were naturally conservative. Lol. There's a shit ton of out of wedlock birth, prostitution, lgbt, leftist/marxist ideologies, etc. Mexico fits the ameri-mutt meme better than the US does IMO.

If the alt right ever partners with Latin america it will be on a case by case bases not the bulk of the populace. My guess is only 20-30 of the Mexican population is salvageable in terms of genetics and ideologies. Which is more than enough to destabilize the country and take it back from the Jews so that's good.

The current Mexican population is largely descended from the 600,000-700,000 Spaniards who settled Mexico in the 17th century and mixed with the natives. It seems really strange. If we were to believe this, it would mean Mexico has more people with ligh features than Italy

Again. Not sure why this is strange. If you've been to mexico you'd see the light skin. Light features though does not make someone white. The mixing that those Spaniards did has affected their europeaness. I would also recommend reading Frederick Jackson Turner's Frontier Thesis.

https://en.wikipedia.org/wiki/Frederick_Jackson_Turner#Frontier_thesis

Those 600k Spaniards were not the finest Spanish breeding stock. They were people that Spain wanted to get rid of. A big reason Europeans explored was so that Monarchs could use frontiers for their less than desirable to go to. Thus reducing the cost of building prisons or changing peoples political stances. So you get 600k low quality Europeans mixing with millions of natives and some sub saharan slaves. It's not the best recipe.

On flip side though, Mexico's fertility rate fell beneath replacement levels for the first time in 2019

We are seeing this in all industrialized countries though. It has less to do with genetics and more to do with the sterilizing affect of liberal values.

The great flood of Mexican immigration to the US will dry up soon.

Directly from Mexico yes but not from the rest of south america.

Chinese top tier cities have first world living conditions, and Korea and Japan are first world countries with better living conditions than the US. There won't be too much immigration from East Asia.

Again. Read the frontier thesis. All empires produce immigrants because it's a natural fit to the solution of what to do with the refuse produced by hierarchical/merit based systems. In the past you'd use a lot of less desirables as canon fodder but we don't seem to have war anymore either so that's out of the picture.

India and Africa will be the main reservoir of future immigrants.

Agreed but we will additionally see immigrants from all large countries. The Chinese just sent a million people to the UK. In fact countries that have the resources to help their immigrants move to other countries will probably top the list. Africa has to rely on international aid agencies (aka Jews) to get their people into Europe.
