My question is why isn’t a big deal made out of Article I, Section 9, Clause 1? Slavery has been a big deal in US and world history, Civil War is incorrectly blamed on slavery. The US Constitution addresses slavery in this clause, importation of slaves was made illegal actually before the 20 year limit stated in the Constitution, importation of slaves outlawed by Thomas Jefferson signing the bill. Some people seem to want to blame all slavery on the South. When in fact Great Britain was a massive financial beneficiary of slavery which studying this clause would allow Professors to expound and point out. Not to mention slavery is the second oldest profession. Actually studying this Clause could lead to a current discussion on economic slavery which is going on now with the Federal Reserve, continual Wars, Ukraine, Libya, Iraq, Syria,W2 War on Japan nuking which includes the theft of 170 tons of gold from Japan, Golden Lily Gold, NSA, DHS and on and on. Just think Article I Section 9 Clause is missed teaching opportunity.
