But what 'work experience' is a job at Disney paying $15k/year? The same "experience" as working at McDonald's. Would your suggestion be any different if the OP said she was looking at getting a job at the local Dairy Queen/McDonald's flipping burgers and making $15k/year?
Does it give you some experience? Certainly....but as I and others have mentioned, who gives you the impression as being more of a go-getter: someone who graduates and settles for a minimum wage job at Disney doing the very basic of things (taking orders at a kiosk) for 1-2 years, or someone straight out of college with decent grades? The fact that the minimum wage worker apparently didn't have any summer jobs during school would be enough of a worry about lack of ambition (the OP didn't clarify - since he didn't say "she did have some previous minimum wage jobs, so she knows what the job would be like", we can only assume that she has ZERO work experience).
You know the first person probably wasn't that motivated to get a more challenging job. If someone isn't that worried about earning more than minimum wage for themselves, how much LESS are they going to be worried about making money for you, the employer? Or just doing the minimum to get by? (Obviously, if it's 2010, there could be valid reasons for not getting a more challenging job right out of college when you graduated in 2008/2009, but this is a different scenario).
Working for the Peace Corps is an entirely different decision/factors than making minimum wage at Disney - one is almost always a volunteer position to 'give back' and be selfless, and a decision you go out of your way to make. The latter is more likely to be just a 'clueless' person who doesn't have ambition and doesn't really care about their (or their employer's) success, or a decision out of desperation. Again, there are always exceptions with people who are truly driven, but we are talking about the 75%-90% of the crowd here, not the 2% rare exceptions.
