Good, good. We are now up to 61%. I've seen a 1% increase in your estimate in just the last 20 minutes of reading your messages. :)
Nonsense, you've simply ignored the fact that even the 61% reported by my source is certainly wrong, proved wrong by the fact that US exports declined only 30% net when all "Southern products" were eliminated, in 1861.
The real number for "Southern products" in 1860 was just 30%, not 50%, not 61% and certainly not the 72% or 83% you claim.
All reports of "Southern products" greater than 30% are simply including exports that were in fact produced elsewhere.
So your whole economic justification theory is based on lies, FRiend.
