Here is the problem:
If you are wealthy, you are allowed to be average. Poor people have to be superman/woman and we won't expect anything less than them.
As for minumum wage jobs, we need people to sweep the streets, pick our fruit, bag our groceries, etc. I venture to say these people have more of an impact on your day to day life than some guy crunching numbers for some corporation. If someone is working, they should be able to support themself.
