What Would It Be Like Today?

What would it be like today, if the Founders had found a way to abolish slavery in America in 1787, with the adoption of the Constitution?  Among the flaws and fallacies within history's greatest document of governance, the foremost is that slavery was allowed to continue.
It wasn't just Southern Caucasoids enslaving Negroids.  Caucasoids owned Caucasoids.  Cherokee Mongoloids owned Negroids and other Mongoloids.  And Negroids owned Negroids.  And slavery was not just a Southern thing.  The slave trade prospered throughout the North as well. 
Lincoln's famous Emancipation Proclamation of 1863 freed less than 50,000 slaves of approximately four million.  And that was accomplished more through military might than by political policy.  It had no jurisdiction in the South, except in those areas already conquered by the Union army, as the South at that time was a separate and sovereign nation called the Confederate States of America.  That is why that that war that pretty much everybody wrongly calls the Civil War was NOT a civil war.  A civil war is a war in which two or more factions fight for control of one nation state.  The War Between the States, or The American War was a war fought by two different, distinct nations bordering one another.  Besides having no jurisdictional authority to mandate policy in the CSA, the Emancipation Proclamation went to great detail to exempt northern states, in which slavery was a thriving business.  It specifically exepted the Virginia counties that became West Virginia.  It didn't affect specific parishes of Louisiana, which were not 'in rebellion'.  The Proclamation didn't affect slave holding in Kentucky or Missouri, as those states did not join the Confederacy. All in all, the Emancipation Proclamation was bullcrap and balderdash until nearly two and half years later, when the force of militarism gave it the force of law.
So, how would American history have changed and how would contemporary American society exist if slavery had never been allowed to exist in constituted America?  First and foremost, many more Caucasoids would have realized that there are more inherent similarities between the races than there are visual differences like epidermal pigmentation and hair composition.  There would probably be far fewer Negroids in America today, as many of their ancestors would have repatriated to their ancestral homelands in Africa.  The ones who would be here would be happy to be here, in the best country on Earth, where they could realize their full, individual potential.  They wouldn't be hung up on race, race, race, craving a culture of collectivism and holding a mindset of vengeful victimization.  And we'd have never had to endure rap.
