In the city of EPCOT, no residents would own property nor would they vote. All the people would work for TWDC (or the various EPCOT sponsors) and Walt (along with his chosen executives) would run the entire show. Unions would be banned. If Walt didn't like you, you'd be kicked out of EPCOT faster than the launch of the Rockin' Roller Coaster. Sorry, but it would have definitely been a total dictatorship.
It was all about doing things the way Walt wanted them done without any pesky outside influence from shareholders, politicians, unions, government or other godless communist agitators (as he called them).
