Again, a min wage job isn't a career, it's a start to a working career, and yes, having those first jobs does enable you get other jobs, including (once having the needed education, training and / or certifications) accountant and pilot.
College isn't for everyone. There are some folks who are more interested in, and have a natural aptitude for, working with their hands and their minds. There's a
shortage in the skilled trades. A young person approaches a master of the craft for an apprentice position. Do you think his chances of getting that apprenticeship is better or worse that he's held a min wage job? I'd content that his chances are better.
I have seen this happening in real life. High school guy is interested in cars. He started as a 'shop helper', cleaning and organizing, up to detailer, saving his money started buying his tools, took training and certifications in automotive repair, and how he's a well paid automotive technician.
If College bound, a part time job during school can help, allot. Having those first jobs betters the person's chance in getting these jobs as well, don't you think?
Did you not work your way up from lower positions to higher position in your working career? It's the same thing, with, I'm guessing, a slightly different start. It's what the person makes of it, the opportunities that come their way (they always do) and the ones they take advantage of.
