I live in a relatively small building whose residents tend to be professional types. Lawyers, actuaries, teachers, doctors, bureacrats, etc.

Of course, a building needs repair and upkeep. One thing I've noticed consistently over the years is how dismissive most of these white collar types are of anyone doing repair work. While many of these people are making good money in fields that often provide a fair amount of job security, they get indignant when a tradesman of repair man delivers a bill for work done.

The idea that a guy working with his hands should be able to make a good leaving seems to peeve these people to no end.

Any kind of mechanical aptitude and training is a highly marketable commodity. If any of these white collar geniuses could actually do anything for themselves, it would presumably drive down the price of blue collar work.

But they can't, or won't, then they squeal like hell when someone who can do the work expects payment.
