Beyond that, in regards to slavery, WWI, WWII, etc. it really is impossible to say how it all would have turned out. I can think of a dozen different scenarios, as I'm sure you can. The greater point is that you probably could have achieved all the same things without murdering your countrymen. Slavery was abolished sooner and with less bloodshed literally everywhere else, and the Founding Fathers were the ones responsible for the widespread belief that treason and violent rebellion is some sort of moral democratic duty (the tree of liberty etc). It is no wonder that things got so messed up - the Founding Fathers spread a creed of violent, antisocial individuality. Even today your national mythos are a poison to the civic body.
Dumb radicals who spazzed over nothing.
