Never said they were.
However, you said “Engineering schools are not “colleges,” (which are also filled with dumb jocks and legacies.)”
which is difficult to interpret.
There are very few Engineering only schools - Harvey Mudd College comes to mind. Almost all are part of a big ‘U’ usually a big ‘state U”. “Big State U” does have its jocks, etc. occasionally they wander into the engineering programs and even more occasionally they graduate.
My youngest is 10+ years out of a state university engineering school and is pulling mid-six figures in programming at one of the largest financial services information firms in the world. His colleagues are of varying nationalities but over half are Americans.
