Okay, so with your updated numbers (estimates), my math stays pretty much the same.
Your point about WV not comprising a single large city? Going by population alone, there are four cities in this country with a higher population than WV - NYC, LA, Chicago, and Houston.
Proximity to large population centers? Within four hours of Morgantown: Columbus (787K), Cleveland (389K), Pittsburgh (305K), DC (658K), Baltimore, (622K) - 2,761K. Huntington: Lexington (310K), Louisville (612K), Cincinnati (298K), Columbus (787K) - 2,007K. Not a particularly large difference, other than Pittsburgh being 50 miles closer than Lexington is to Huntington. Not that it matters, since Marshall (80%) caters to WV students, while WVU (49%) clearly does not. In case you were wondering, despite being twice the size as Marshall by enrollment, only 3700 more WV residents attend WVU than MU; ~14,300 vs ~10,600.
However, all of this distracts from the main point, and is ultimately irrelevant. The pop tax is a state tax (NOT a WVU tax) which goes to support medical education in WV. When the tax was created, there was only one medical school for it to support. Fair enough. There are now three medical schools. And none of us are necessarily in support of splitting that one penny per bottle of pop three ways. Throw two more pennies on there, one for each school. I'm sure nobody would mind paying $1.39 instead of $1.37 for that bottle of Coke. With inflation, the tax is still less than it was when instituted -
one penny in 1951 = nine in 2015.
When I pay my taxes, I expect the government to use them in a way that benefits me in some way. That's the entire point. I'm well aware it is naive to think that actually happens, but I still want it to work correctly.
For all of your talk, you are the only one I've seen here who is against working together. We want the state to be less obvious about it's bias, and give us a fair shake. The only thing you can think of is "Let's work together by having you shape up, or face the wrath of WVU. Stay away from our money." I am all for cooperation between the schools. I'm in Morgantown every month for work, and have a number of friends who are WVU students or alumni, which has given my a much more positive view of WVU than your average MU alumnus. However, it is the people like you who seem to believe that working together means having WVU dominate any collaborator on any project, who keep making any cooperation difficult.
