Caporegime
My neighbour is a financial director for a well known organisation, his wife checks the oil in his car, cuts the hedges, wipes his butt basically. He lacks any skills outside of his profession in short.
That's not necessarily a sign that he lacks intelligence in other areas, he may just be good at delegating tasks he doesn't want to do or very manipulative. I find the argument strange that people who earn well and can't do DIY and what not lack common sense, maybe they just don't want to spend 8 weekends in a row renovating their bathroom and doing a poor job of it when they could pay or use someone to do it properly?
