Menial is a revoltingly sneery word.
I can't imagine ever using it in conversation and I would worry about any person I heard using it and it would make me judge them as snobs frankly and rather stupid and definitely insensitive.
Yes it has origins and yes it has a meaning but it is only ever used to diminish the category of person it refers to. Nobody has ever used the word menial as a compliment or as praise.
Every job that needs to be done is important - and some of the jobs sneered most at are the most important ones.
Cleaning for example - hospitals lose patients at terrifying rates after surgery due to infections caused by inadequate cleaning because cleaning is NOT low-skilled and requires a certain amount of intelligence and dilligence to be done properly.
What on earth is the point of a highly-skilled surgeon battling for hours to save a patient's life for all their work to be wasted when that patient dies of an infection caused by bad hygiene practices?
I myself caught a digusting infection after an elective caesarian - because the toilets in the hospital and the ward itself were filthy.
You can't 'not pay attention' to jobs like this - you have to do them properly or there are consequences.
If more people respected the tasks they do and if people were encouraged to respect every job of work done then maybe people would choose to do so-called low-skilled jobs who might otherwise avoid them. And maybe they would be happier doing those jobs for all sorts of reasons. Personally I think people who work looking after people in homes are doing an incredibly important job that requires huge resources of patience and skill to be done properly and I respect anyone who does that job well.
I have a high IQ and was pushed towards the professions as a girl. I am someone who might easily have ended up a surgeon. I would also say that people who think that surgeons could easily do the job of cleaners are mistaken - I spent plenty of time with people who were destined to become surgeons and while they may be excellent at the niche skills they train for they were extremely clueless in general life skills and many of them were not even capable of basic household tasks and would recoil in horror from anything germy. Remember they are used to dealing with sterile environments and wear gloves and masks to protect themselves. So cleaning is unlikely to be one of their skillsets and they would probably not do it well at all.
I went to dental school to study dentistry. But really I wanted to be a hairdresser or train to make jewellery. I spent decades faffing about starting various 'acceptable' careers for someone of my educational standard because I'd been conditioned to think I had to seek a prestigious career. I had a bash at Law and IT and I was a maths & science teacher. I could do any of these things and I could do them well but they made me miserable.
Now in my fifties I'm finally realising that any job that makes a person feel contented at the end of the day and any job that makes a person feel like getting up in the morning is the best job in the world. All this dividing up of tasks into 'high status' and 'low status' harms everyone no matter what status job they find themselves doing.
Of course some people get more money doing one thing than another but anyone who calculates the value of anybody else as a person based on their earning capacity is someone I consider shallow and ill-informed.
For exampleI know who I would consider more valuable to the world out of Donald Trump or Vincent Van Gogh.
