My boyfriend in high school went to a Catholic private school and I went to a regular public school. He boasted about how his education was better than mine because his parents paid $10k a year in tuition fees on top of uniforms, expensive field trips, and textbooks. Meanwhile, looking at his bookshelf one day I discovered that he had all the exact same textbooks that we used - for free! We both graduated with similar grades (high) and went to the same university (a very prestigious one). I'm by no means a "hard worker" and neither was he (although he was a harder worker than I was and was generally one of those smart know-it-all types), but we both learned the same materials and learned them well.
It saddened me a bit that his parents actually started saving about $7k a year once he went to university. We broke up after university because I just couldn't stand him anymore, but that's a whole other thread.
Oddly enough, after university he went to teacher's college. He had a hard time getting in because of his demographic (white male) and someone from his church pulled a few strings to get him in after two denied appeals for admission. He graduated from teacher's college at the top of his class but couldn't get a job with the school board (6000 graduates every year competing for a very small pool of jobs). As far as I know, he is still running a daycare for $12/hr, waiting for a job teaching high school. He graduated from university about 6 years ago.
I went into publishing and got a job in my field right away. I did that for 2.5 years before I got the balls to quit the corporate world to follow my passion for working with animals and start my own business. I now run a very successful dog-walking business and I teach puppy classes and do private consults in the evenings.
Long story short, I know that life is what you make of it. My kids (if I ever have them, still on the fence about that one) will go to public school.
