When I was studying computer science, they told us "If your program doesn't work, don't bother to turn it in because you got an F. And if your program brings down the system don't bother coming back, because you have failed the course."

But I can't get a job because people are not interested in hiring programmers who write programs that work. Microsoft have a vested interest in selling crap because they they can con you into buying upgrades and support.
