One night I was talking to an older friend of a friend, 50+, around a year ago now. We were talking about what we did for a living and what we got paid. We started off with what he did: He's a bricklayer, nothing more, and told me that they get paid per brick they lay. It's something like £4 per brick. What shocked me was an experienced bricklayer like him usually lays enough bricks to make around £400/day.
"That's almost £150,000/year!" I said, trying to not sound too envious or anything (spoiler: I failed). And this doesn't include the one-off jobs they get every weekend from rich foreigners who have extravagant houses built in the UK all the time. All in all it can amount to some very large amounts of zeros in your bank. In a few years he became a millionaire from bricklaying. I have since then talked to a few others who are in that trade and it all (anecdotally) corroborates, approximately (the older you are the more you get picked for "specialist" properties that involve very rich Chinese and Arabians apparently, which can make you ~£1,000 in one weekend).
I asked, as any sane person would, something along the lines of "why isn't everyone and his dog laying bricks?". And the reply was very intriguing. He said essentially that younger people these days (my age) don't want to lay bricks every day now, or don't have the stamina. They want to go on their phones and become world-famous and important and work on new gizmos and apps every day and be looked at by everyone and be payed attention to, etc, etc.
Since then I've not really been able to get my head around it all. It seems like although we talk about automation stealing jobs and everybody will have to be a "techie" to make any sort of decent living, there is definitely a small "elite" minority doing these very old-fashioned jobs that no-one wants or can do anymore. I fear sometimes that we (the younger generation) are slowly going mad with technology, and forgetting about the practical skills. What our own two hands were made to do so to speak.
We never got on to what I do in the end funnily enough.
Anyway, more relevantly, this lumberyard article is just a (slightly Americanised) theme of the above. It's these jobs that were done for a pittance in the past (sometimes even by slaves and prisoners), and now are these trades that sometimes are paying exorbitant salaries, just simply because nobody wants to do it, because no-one can be bothered anymore.
Apologies if this was long and off-topic, but I hope it's left some kind of thought somewhere.
