I agree that it's an apples-to-oranges comparison, but maybe not in a way that casts Disney World in a positive light: it seems like the primary experience of Disney World is queueing for hours on rides that are references to things you already know, and paying a general "Disney tax" for being surrounded by familiar intellectual property. That's some people's thing, but it's not mine.
State and Country Fairs, on the other hand, are relatively diverse in their attractions: you can do the carnival stuff if you'd like, or you can:
* Peruse your state's agricultural and crafts competitions
* Go to the livestock auctions
* See live music by local artists
* Go the the trade halls and look at/purchase goods by local businesspeople
* Attend the live performances and competitions (my favorite county fair[1] has tractor pulls and pig races)
