"Deserve" has nothing to do with it. You might think they deserve $18/hr. I might think they deserve $30. The market determines what the wage should be based on the service being offered. Disney has been raising prices for the same reasons all of us have experienced over the past year. Food costs have gone up, the electric bill has gone up, fuel has gone up, ,etc. etc. Now we need to compound it by raising wage costs to some number that random internet pundits think is fair vs. the people who actually run the business, know the short and long-term plans and understand the market they operate in? Many in this discussion act like CM's are slaves who have no choice but to work for Disney and take whatever they are given. They are free to go work at Universal, Walmart or anywhere else. If enough workers find a better deal elsewhere, then maybe Disney adjusts to offer better compensation or benefits. Apparently, they feel there are enough people willing to accept what they are offering that they don't have to offer more than they have. They may be wrong but so far, more and more attractions and services are reopening so they must be getting those employees from somewhere.
Disney has been raising prices to increase their profits. I know this because when all those costs in the real world start to go down (and they have) Disney doesn't then reduce their prices.
