20-30 years ago I read an excellent book, called Dumbing down America.
Reduced expectations, reduced rigour… even English college students were encouraged to have free flowing thoughts and absolutely no question of them being pulled up on lack of grammar. Playing with grammatical rules and constructs for effect is one thing, but you have to know the rules first… at least you would think so if a college major in English.
Becoming more and more widespread.
Few years ago I went looking for a copy of the old leaving cert log tables - which were wonderfully detailed, trig functions on the covers, thin paper so light, full tables of logs, sines, cosine etc… the modern ones are absolute shite.
