First, I want to say I have worked minimum wage jobs, sometimes more than one, and I was working these jobs over a period of time when our state had several minimum wage increases.
It was my personal experience that I never stayed at minimum wage for long, however, I at least twice was returned to it when it came up to what I was making. It was very frustrating to work at a company for a year, receive two raises, and then have a brand new unproven employee come in at the same wage I had earned through raises, just because the minimum went up.
Second, I do agree that there must be some minimum wage, and that there should be some level of increases, at a regular interval. I think the level and increases should be set by the states. It has already noted through-out this thread that many states already have higher than federal minimums, and it certainly varies from state to state, what a reasonable wage would be. That said I do not believe that these increases should be large, as it would undeniably cause a certain amount of inflation in and of itself.
Lastly, as mention several times in this thread, it is a MINIMUM wage, not a LIVING wage. It is a wage meant to provide SOME income to an individual.
It is true that in the "real world" many of these jobs are held by those with families, and that is a sad situation. It does not matter whether they are in those jobs because they lack the skills, are lazy or are in an area where no better jobs are to be found, they are there because there are jobs that need little to no skill and more people to fill the position if they leave.
Just a side note: Many of the people I have known to have the best work ethic are people who started working young, as a Newspaper Delivery Person, or in a "work permit" position washing dishes or sweeping floors. These jobs are getting harder to find, as at least here the newspaper routes are all given to adults and delivered by car, not bicycle. Even the "Traditional" teenage burger flipping positions are being filled by the over 30 crowd.
I for one am over 30. I graduated high school with a 2.0 GPA. I tried community college; it was not for me, at least not back then. I started ground level at minimum wage and learned a trade. For health reasons I needed to change professions, so I learned another and am on career path #2 of who knows how many. I make a living at one job, I would not be satisfied flipping burgers at this point in my life, I often wonder why they are, or what magic advantage I had that they do not.
