Not all, but many are. To make things worse, one of the places I went to is not a "popular" school. Maybe they lack a football team.
Folks here, not having heard of the place, have at times made remarks about how it must be a no-account, third rate place- unlike the fine local school, of course.
I point out that the school belongs to an association of similar schools, that the entire association has but ten members.... and, oddly enought, the other nine they all agree are 'top of the heap' places.
That's when I say "don't blame me for your ignorance!"
Seems to me that 90% of education snobbery is pure ignorance. The same folks also probably consider the trades to be somehow "below" them. When they do attempt to do some work.... you'll likely see pics of it in these forums!
