Not everyone gets the job of their dreams. We all know that. But every student can leave school, go to college, go to uni, graduate, and get a fulfilling and well paid career. I did all of that, with no funding from my parents. Student loan and part time job got me through.
Doesn't matter what your background is, there is nothing actually stopping you.
Whether you go on to get the top, top jobs, the establishment jobs, well that's a different argument, but everyone can have a good career if they want one.
