I think the youth are too short-sighted, thinking that these are the only jobs they are ever going to have.
Like someone said earlier, I also did menial jobs in High School and it did teach me that I did not want to do them when I grew up.
Well, consider what the job market has become these days. I can speak personally about my situation: I've worked at my "menial job" at a grocery store since high school. Honestly, I like the work; it's more complicated than most minimum-wage jobs are and I get to be creative. I just don't like the minimum wage pay.
I even went to college. I had a whole plan for my life: get a bachelor's degree in meteorology, get my foot in the door at a small-market media outlet and either find a steady home or work my way up until I did. Well, I got that degree... just as the recession hit. I was locked out of the job market, my applications were basically all ignored, and I ended up going back to that grocery store. Now I see what the jobs I wanted have become, and they're paying practically minimum wage, with a lot more corporate demands than there were before; even if I had gotten in I wouldn't have had the kind of middle-class life I had planned on. It was the biggest mistake of my entire life.
Yet I have no idea what I want to do now. My degree's practically worthless and my talents are all things that don't have a realistic chance of me finding steady work. Most jobs around here require ridiculous amounts of experience or prerequisites so specific no one qualifies.
So yeah, that idea that there might not be anything better? That's real. Without connections, the job market is daunting and flat-out demoralizing.
