It seems that by 'rich' the article referred to professionals with high salary. I am not sure how much I will call rich someone that needs to work on a job to continue having an income. 'Prosperous', 'well off' sounds more accurate, but English is not my mother tongue.
My point is that the rich, the ultra-wealthy, can pass assets and business to their descendants and can pay their children's way into exclusive institutions.
I prefer a society were everybody have a minimum well being guaranteed and better off people just have some more luxuries.
