>The Establishment would rather weep over the poor persecuted Negroes, but leave the White working class "rednecks" and "crackers" (both of these terms of derision were first applied to White slaves), to live next door to the Blacks.
This isn't completely accurate. The terms "redneck" and "cracker" predate the slave trade.
"Redneck" originated in Scotland where rebels in the Bishops' Wars wore a red kerchief around their necks to signal their rejection of the authority of the English bishops.
The name stuck with that population and their descendants who immigrated to the southern United States.
"Cracker" comes from the Irish word "craic" meaning fun while drinking with friends, which comes from the middle English word "krak", meaning loud, boisterous talk.
Modern terms which share the same origin include "wisecrack" and "crack a joke".
