I don't know why you keep attacking your straw man - the argument you attribute to everyone else that CLT will be shugt down and everyone will be asked to connect at MIA - but it's a free country and you're free to make any number of erroneous arguments.
As to the chart you found on Flyertalk - note that it includes only domestic O&D, and does not include any international O&D. If I recall correctly, Miami has about 10-20 times the international O&D as Charlotte.
As others have posted, some of the CLT international flights, like Rome, are filled primarily with O&D to/from South Florida, not CLT O&D and not O&D to/from the small towns in the Carolinas for which CLT is the only logical connection point.
MIA has huge international O&D and CLT has almost none. That's why CLT won't have a wide variety of international flights next year. LHR, FRA, CDG and MAD - certainly. Many of the others? They probably won't return next year.
So how will people in CLT get to European cities not listed above? Either via PHL, JFK, MIA or they'll connect in London.
The AA execs in CLT (actually US execs) told Charlotte in June that CLT had the lowest unit revenue of any East Coast hub. That's not encouraging news for the future of CLT.
Before you go beating that straw man again - I'm not saying that CLT will be STLd or PITd or CVGd or MEMd or CLEd. CLT just won't continue to grow exponentially and may in fact shrink now that Parker has higher-yielding hubs at his disposal, like NYC and MIA.
