You have to understand that the USA doesn't value its workers. Disney is just like any other large, souless corporation except it is one built on the illusion of family and family values.
People in this country like to kid themselves into believing that 1.) we are a compassionate nation (when any look into the way we treat the most needy would show otherwise; and 2.) that we live in a true democracy ( we don't ... we live in a capitalist society where big business is allowed to control the playing field.
There's a reason why WDW's workforce now is almost the polar opposite of what it was 20 years ago. It's simple: you don't have to pay a living wage to high schoolers, College Program kids, retirees and people working 1-3 shifts a week. Of course, you may pay them $7 an hour and luck out and get great workers because they don't need the money, but alas some workers do this as their job (or second or third) and do need it.
The only thing preventing WDW from having a liveable minimum wage (in Orlando it would have been $9-10 an hour before Bush got his dream of $4 a gallon gas) is simply the fact Wall Street's institutional investors would not allow it. Again, that's what happens when big business takes over a country ... and it may be a FREE market, but it assuredly isn't a democratic society.
