General Lee could have been on the right side of history and he chose secession.   General Lee's wife owned slaves and he could have given them their freedom, but he chose not to do so because of the heavy debt to the banks.   He wrote a letter to his wife and said the blacks were slaves to the whites and the whites were slaves to the blacks.  The economy in the south was based on king cotton and others commodities.  

 There should be a statue of General Meade that defeated Lee and his army at Gettysburg and this was the turning point of the war.   If Trump was asked about Meade, he wouldn't know who he was.   The US was built on blood and sweat for profit.
