> At that time labour was cheap I was curious about this, but also a bit lazy, and the easiest figures to find were for the US. A carpenter in 1921 in Boston MA (which is upper-end of the range given, but not outlandish) earned $1/hour or $40/week. According to this[1], that's $17/hour or $680 a week. That's just over half of what they get paid now, at ~$30/hour. As to: > At that time labour was cheap For the random example I picked, in the US, labour was about 50% the cost it is now. 0: https://fraser.stlouisfed.org/title/union-scale-wages-hours-labor-3912/union-scale-wages-hours-labor-may-15-1921-492986?start_page=68 https://fraser.stlouisfed.org/title/union-scale-wages-hours-... 1: https://www.usinflationcalculator.com/ https://www.usinflationcalculator.com/ 2: https://www.indeed.com/career/carpenter/salaries/Boston--MA https://www.indeed.com/career/carpenter/salaries/Boston--MA
