Many middle class parents don't realise qualifying in a trade can get them more money, higher job security and potentially higher job satisfaction.
A lot of it is also snobbery. In the Blair years, we got one of those "technical" secondary schools built near us, which was supposed to be aimed at the less academic pupils to learn trades and practical work. It closed after about 5 years because of low numbers of pupils. Parents simply didn't want the stigma of their little darling going to such a school and potentially doing a "dirty hands" job. They'd far rather they struggled, got MH issues due to not being able to do the school/uni work, and end up either crashing out of Uni, or working in a call centre or shop with their low grade degree.
My sister was that type of parent. It was clear from an early age that my nephew wasn't "academic", but my sister pushed him and pushed him and he managed to scrape a few "passes" at GCSE and then did A levels in which he crashed and burned, being thrown out of sixth form after the first year. She still didn't get the message, and pushed him into going to the local college of FE to do some kind of business studies diploma, in which he struggled and crashed & burned, being thrown out after the first year, again. Since then he's done a succession of minimum wage jobs, including van driving, shop work, etc. I said many times during his teens to her that she should suggest he went into the trades, but she was having none of it - apparently he was "too good" to be a tradesman! In the next breath, she whinges about how expensive plumbers are and that she can't get a decent one and also the cost of having a TV aerial installed a few weeks ago saying the same as people on here, that "why" do plumbers, aerial installers, etc charge so much!
She really doesn't see it! The thing is that nephew would have been a brilliant tradesman, he's always been into doing things with his hands, does a lot of work on his own and his friends' cars (sister also complains how mechanics are too expensive!), has done a lot of work to his home, etc.
We really need to tackle the snobbery about "hands on" and practical work.
