It's probably true if you own the company, but there's also disgruntled folks who apparently got treated like shit during their apprenticeship and who snicker at their former employers or dissuade would-be prospects when their field isn't doing well (boohoo poor Porsche drivers) or when they try to advertise a craft. At least the YT comments under several blue collar documentaries/adverts say so, but I know none personally.

Then there's an ongoing crisis in construction due to widespread financing problems (need two decently paid full time earners, no kids, to afford it with some certainty and no 30+ year debt slavery at least around where I live) and assorted crafts.

An electrician friend is doing okay, but not exactly great, at barely more than 40k pre-tax per year. Another one who is farmer on the side (can't afford to live from it) makes about as much in his profession (mechanic). I.e. forget single earner family and/or mortgage.

It's difficult to gauge accurately, because statistics are complicated and/or shit and/or biased, the employment situation highly depends on region and field and things seem to be changing at a crazy pace, not least caused by the recent economic shocks (war, COVID, a decade+ of QE), problems with funding pensions/bad demography, increasing competition in core industries, high energy prices and political indecisiveness. How much each factor contributes remains a mystery to me. Wealth m/billionaires seem to be growing fine.

Personally I'm more and more convinced there's no conspiracy and things really are as bad... The Japanification of Germany. At least our debt isn't as high yet.
