Let us do that without throwing the constitution to the wind. Lincoln, while good intentioned, was willing to throw away established constitution rights for his narrow-minded and rather unpopular view of State’s rights. Since that time it has been down hill for our nation. All you need to do is look at any major American city to see the results.
Can you be more specific?
Actually the US after elimination of slavery was uphill for a long time, at least until the creation of the federal reserve in 1913.
The US growth rates in the 1870s, 1880s were very very high. Reconstruction was in many ways a time of good government for the south.
