You can take your White Supremacist garbage elsewhere. Money gives huge advantages in education.Even the dumbest of kids can get good grades with unlimited private tutors and lots of free time,privileges poor kids don't have.
So if a student has a single bad day at the end of the class then they can effectively flunk. The intent of grading in an educational system is to keep track of progress over time and provide insights & assistance as necessary to students to improve their learning. The idea of teaching a class for an entire year with no homework to review, no accountability during the course of the year -- with only a final examination at the end to determine the grade is ludicrous.
Your chart just confirms what I wrote. High IQ will ultimately lead to higher median income. Asians started out poorer because of discrimination and language barriers for the first generation. Your 'white supremacist' nonsense is laughable when I am pointing out that Asians have the highest IQs. You are the racist by calling them 'robots.'
High financial means leads to better education and lead to higher median income. I know you thought Trump winning would be the end of AA and DEI but it isnt.
The 'graduates' of such schools are in for a nasty surprise when they find out skipping workdays and handing in late assignments get them fired in a real job.
