Grades used to as a barrier to keep people out of university, and thereore out of jobs, is a huge concern. My dad is one of the smartest people I know and he went to university with a high school average in the 60% range. He's a high school teacher now and, by all accounts, an excellent one. It's worrying that people are being kept out of good jobs simply by not having high enough grades in high school. I know parent's who require their kids after school tutors to have a master's degree for god sake.
This whole phenomenon is called credentialism.
