People forget how much the average IQ of the united states has dropped in the last 50 years. That the primary reason and it isn't fixable. It will be worse. 95% of society enjoys a standard of living based on the work and inventions of the 1% hi IQ members of society. When you shift the IQ bell curve 10% you reduce the number of hi IQ individuals in society by 99% because its a bell curve IQ distribution. This means there are 100 x less smart people and that is below the number needed simply to MAINTAIN inventions and infrastructure previously adopted. Shit begins to fall apart and be unfixable by enough people in the society. This happens in the legislative bodies as well. There aren't enough smart people elected who know why certain basic principle like freedom of speech exist. This is happening on America now as more and more idiots are in the legislatures. Soon there will be laws mandating voodoo and things. The majority of the population won't be able to make logical assessments. That is probably already true given the covid vaccine acceptance by most people. Then things become more and more herdlike behaviors and tribal wars. Every year Africans in one country go out in their cast off American blue jeans and t shirts and shoot arrows at each other for scraps of the same farmland. They do this because they can't think to cooperate and raise the output of the land to more than feed them both. Sort of explains US politics today. And white people aren't having kids so it will be really really bad in 30 years after the majority of white people have died out. Its going to be even more of a zoo. Hi IQ people better figure out a new place to go or carve out part of America. Might already be happening as so many leave for Florida and a few other red states. The alternative is South Africa where the white people live among little more than savage monkeys that pick them off one at a time.
