Asians account for 1.8% of Fortune 500 CEO's, despite being 6% of the overall population and 20-25% of the enrollment at places like Harvard or Stanford business schools. Not quite white yet by my estimation.
Since the 1970s the Asian population as a percentage has grown more than 5x (greater multiple than all other demographics) You would expect that if the median age of a CEO is in the 50s the enrollment numbers of Asians back then (1970-80) weren't expressed nearly as significantly. So still sounds 'white' any estimation.
