Your comment reminded me of going with my dad to a place that had a huge laser-cutting machine when I was young. They were awesome!
Something that blew my mind recently is that I left joinery with a job earning about 65k CAD per year (around 2008). I recently met a guy getting his red seal and he earns about 62k CAD. He hopes to hit 80k within a few years of getting his seal by making lateral moves and bargaining better, but isn't certain it's even possible. This is insane to me. Not only has the value of his work decreased, but even with better credentials than I had he's earning less. This is the completely wrong direction for things to go!
I was also shocked to find that he spends about 36% of his pre-tax income on rent, and when I was earning 65k I was spending about 8% of my pre-tax income on rent. I lived an hour away and shared rent with a room mate in a small house, whereas he lives alone in a small apartment in our expensive city. But wow. What a striking difference; it almost seems impossible to get ahead despite that he's educated, competent, and working hard at improving himself. I feel like that needs to change or we won't see kids move into the trades and, you know, hold up our society here!
Also I totally agree about giant laser cutters. I can't get enough of CNC machines of all sorts. I really, really want to build one some day.
