I'm all for paying the cast more because they do a great job and have to take alot of c**p from people all day. However, $10 per day would leave me $140 per person out of pocket for our two week vacation which makes the whole thing very, very expensive. Selfish perhaps but If I think like this so will 1000's of others which would severly change the figures you quoted and, as such, Disney would not be able to afford the increase in wages.
Forgive my ignorance about the US pay / tax / NI system but I think I am right in thinking that raising an additional $3 per CM per hour does not mean that a CM will actually get the full $3.
Youre correct. When i get a raise from my bosses, usually the taxes take it all. But i got a raise nonetheless.
