In the suburb where I live, the students typically have well-educated parents who instill in their children the importance of learning and doing well academically. The parents attend school open houses and teacher conferences religiously. Not surprising, the students here score well and over 90% go on to college.
Contrast this with those locales where the students' families are less educated, less affluent and do not have the time, energy and/or interest to support their children's academic endeavors. Put the same teachers in each setting -- think it doesn't make a difference?
Nat: Put you in a radio station where all the equipment is basically junk and you have antiquated or shoddy tools and training materials to refer to. Or, put you in a station with advanced, well-maintained equipment, tools and training materials. Think it doesn't make a difference? How would you feel if, in the former situation, things don't go well and others conclude, "Nat is a lousy radio engineer." Would that be fair?
