Who are jobs for?

I've worked 23 hours in the last four days and I'll soon be off to work four more. I'm quite tired, retail is a tiring job, not as tiring as most but more tiring than many would think. You need a permanent smile and a lot of patience. But more than anything I'm tired because there are many nights when I finish in the early hours of the morning... and I'm an early-bird by nature.
I work because I need the money and I will no doubt continue working throughout the year. Yes working in a convenience store isn't the most gratifying of jobs, but I'd never say that I'm too good for it. I must have taken that from my dad, he needed money quickly so he worked in McDonalds over the summer; he's 45 and with an unfinished doctorate who on Tuesday started working at John McGlashan college. He has no qualms and I'm proud of him. He is the sort of person, with a higher than average education who doesn't think that he is better than anybody. He treats everyone with respect and isn't proud, in the christian sense.

I'm not totally like him but I felt very insulted when an old teacher of mine, buying smokes, told me that there were better jobs out there. She saw this job as a lower-status, uneducated, low-paid piece of trash. Instead of telling her that there were much better ways of spending her money than on smokes, I told her that this job is in fact alright. It pays higher than minimum wage and yes the hours can be quite bad, but the working atmosphere is good, the bosses respect and apreciate us and anyhow, there aren't any jobs out there frankly. I will continue looking but I'm not going to let go of the one I have.
She left with a shrug and a ta! I stayed at the counter thinking what a horrible person she actually is. All I can think of is that if someone is serving you, all you can show is apreciation. You cannot deem them as stupid at first glance, that is prejudiced. They may be working in one of the highest deciled schools in the country and have an unfinished PHD! You cannot be unapreciative because if you are, they can make your life hell. 'They' is everyone who serves you, if you think you are better you will get served badly. In retail we can do this. I've had people who study at uni come up to me assuming I cannot count so I called them an asshole and threw in some burnt chips.
I'd like to first point out that there is this thing called dyscalcula, which I do not have but I know people who do. Secondly, that an education doesn't make you any wiser, maybe just a bit more prepotent and insolent.

People work because they need money. Everyone would like to work as James May in his ToyWorld, many would like to be paid to read or write bad poems or scribble for millions. However, these jobs don't really exist for the majority of us.

Last, someone once told me that because I'm a student I cannot be a worker. I'm a socialist so that wouldn't comput with my system, but also all students are, are in fact the next generation of workers, our education is paid by the last.
