First of all a civil war that took tens of thousands of lives for nothing, was a very stupid idea (with all due respect to Abraham Lincoln).
'The Civil War was America's bloodiest conflict. The unprecedented violence of battles such as Shiloh, Antietam, Stones River, and Gettysburg shocked citizens and international observers alike. Nearly as many men died in captivity during the Civil War as were killed in the whole of the Vietnam War. Hundreds of thousands died of disease. Roughly 2% of the population, an estimated 620,000 men, lost their lives in the line of duty. Taken as a percentage of today's population, the toll would have risen as high as 6 million souls.'
Civil War Casualties
It achieved nothing, destroyed the South, and gave the rascals on both sides free rein to loot and pillage innocents. William Quantrill's Lawrence Massacre is well-known for the murder of innocents. There is debate as to whether he was "an opportunistic bandit or a legitimate partisan".
2. Had the federal government simply negotiated with the slave owners,
compensated them fairly with cash, and then made proper arrangements for all those who had been emancipated to be resettled and have their own productive settlements, it would have cost far less in cash and human lives.
3. The federal government did not even have a solid plan to rehabilitate emancipated slaves, just like they failed to give the Native Americans a fair deal at that time.
So while they were fighting a war to free black slaves, they were creating red slaves on wretched reservations. More stupidity.

Large numbers of blacks were encouraged to be unproductive by putting them on welfare, rather than creating meaningful jobs and giving them an opportunity to work for other blacks or go into business for themselves. The so-called "War on Poverty" did little or nothing to alleviate poverty.
5. More recently, scheming black politicians failed to follow the example of
Booker T. Washington who did something constructive for his people, and instead they made sure that blacks destroyed themselves in the ghettos. Today, both blacks and whites should read
Up from Slavery by Washington, and apply his ideas. He was well-respected by both blacks and whites (unlike Jesse Jackson and Al Sharpton).
