Well, in the words of Bruce Springstein, "Sooner or later it all comes down to money...."
Waht we have is a history of the wealthiest using wahtever they can to divided us and make us fearfull of others... That is the "divide and conquer" game and they ahve used it as effectivelu as Hitler used the brownshirts in the 30's...
The reality is that 5% of the people have corraled 82% of the wealth and they want to keep it just that way and so they dool out a smidgen of it into various hate campaigns to "keep 'um seperated" and until the other 95% catch on to thei pea-under-the-shell game then things will stay this way...
