Classic thinkers of the 19th/20th centuries that the rich are deathly afraid of have explained decades ago what the root of the problems we are seeing is. It's exactly as Hungry4hops has described it. Everything we see stems from that, including systematic racism and the pinning of different ethnic groups against each other. It's a classic strategy employed by those whose sole goal is increasing their own wealth. Lack of education (work your ass off, pay taxes, go to church, don't ask questions) and perpetuated ignorance is an integral instrument employed by those who want a divided society. Creation of antagonisms and using them to derive additional wealth and power -- that's what they are doing, at everyone else's (whites', blacks', etc.) expense.
