What happened to the USSR during the 1980s is occurring with the United States right now.
During the early 1980s, there was a sharp increase in the population of the non-productive population groups in the USSR (Uzbeks, Tadzhiks, Azeris, Chechens, Daghestanis.etc), while the population of the productive groups remained stable (Russians, Ukrainians, Balts, Moldvins, Mordvins, Chuvash.etc). The pressure exerted by the non-productive groups became too large for the others to neutralize, and as a result the USSR collapsed. The same is ongoing in the US right now.
It's terrible to see you trying to explain something so complex simply with a mere analysis of the populations of a country.
You're summing up things in a terrible way. You forget absolutely everything in fact, taking into account only a shitty argument of population ethnics.
What about global economy? Importance of banks? Change of resources?
No everything can surely be sumed up by an ethnical approach
