most european countries are still predominantly aryan. america is only 52-58% aryan, depending on how many untracked invaders have crossed the southern border thus far. once the invasions in europe ramp up, it will become just as bad a shithole as america has become. you can have a functional socialist society as long as it is also homogeneous. its members will be naturally inclined to participate in economically and socially when it is understood that to do so will help uplift and advance the nation as a whole, along with all its members. when you have a racially fractured society such as america is today, the aryans of the nation will be disinclined to participate the moment it is shown that we do not reap the benefits of our own labor, and that only the protected races will benefit. meanwhile, those races that benefit are disinclined to work for the betterment of the nation because thus far they have received those gifts with no demand of participation in return. this concept was one of the central pillars of national socialism in germany. a single, unified race working together will see more prosperity overall in that system than any other, and that race will improve both societally and biologically as a result.
