A brain dead, well-paying job might seem pretty great in the short-term, but after 20 years? I don't think so. I worked in a public service temp admin job once, and for a while it was great. I could go to work after practically no sleep with a hangover and it didn't matter. After a while though, even though it was a stress-free environment, I became stressed and anxious at the thought of even going. Why? Because I was better than that job and because I felt STUPID. I decided to go back to nursing, even though it was stressful and difficult to do because at least I felt alive.
A job needs to be about more than money. It needs to be stimulating, enjoyable, manageable, a reasonable amount of stress and responsibility involved, and something you're proud to do. It needs to be this way because you're going to be doing it for a long time and because its unhealthy to be constantly unmotivated and not using your brain. I pretty much feel good about myself when I get home after a shift, but on those days I feel horrible, I remember that temping job and wake up to myself.
Those jobs which pay ridiculous amounts for people with no skills or qualifications are usually casual or contract work anyway. Its hardly anything to base your career on.
A degree or trade gives you choices and opportunities, including further study and courses which most occupations require these days throughout your working life.
Unskilled, unqualified people will never have these choices or opportunities.
