I agree, but the cultural factors that lead to achievement among “Asians” are declining. In time we will see a pronouced regression toward the mean unless Asian parents become more aware of what the schools and popular culture are doing.
Achievement of Asians in England is also seeing later generation declining (Theodore Dalrymple)-—the longer they are under the dumbed-down English school system and influenced by their vulgar, toxic culture, the more derelict and worthless they become—and their families self destruct.
Marx is all about destroying all relationships—creating hate and distrust between all groups. Family structure when it influences worldview and can buffer the toxic popular culture can save children. Without family structure—there is no chance. Children are destroyed.
