The first principle of the exploitive mind is to divide and conquer.

 “The first principle of the exploitive mind is to divide and conquer. And surely there has never been a people more ominously and painfully divided than we are—both against each other and within ourselves. Once the revolution of exploitation is under way, statesmanship and craftsmanship are gradually replaced by salesmanship. Its stock in trade in politics is to sell despotism and avarice as freedom and democracy.”
― Wendell Berry, The Unsettling of America: Culture and Agriculture
