How would the US be different if the Confederacy had won the US Civil War?

America would be divded up into 2 countries, the North and South, or possibly 3, North, South and West. "Southern North America" may still have some form of legal slavery today or if not, blacks would be 2nd class citizens.

The last nation to abolish slavery was Brazil late in the 19th century. Clearly the Confederacy even if only for economic progress, would have abolished slavery in due time and proceeded to keep its agricultural economy and also invest in the 19th Century's Industrial Revolution.
