The whole comparison issues is complicated
I think you hit the nail right there. Generalizing doesn't work. The British relied on skilled workers? The Lancaster was designed for unskilled workers. CBAF was designed for mass production, but only made 4 Spitfire models, and made more Spit Vs than I thought they should. Grumman made more Hellcats in just over 2 years than CBAF made Spits, but, the Hellcat was designed to be made, and the Spit was designed for speed.
We can't make a true comparison based on photos, articles and generalities. I once visited Bryce Canyon, and it looked amazing. I took photos, and videotape, and looked at professional picture book pictures, and it wasn't the same at all. I worked in an aircraft factory, and it's a big, complex place. I remember the smell of the upholstery shop and the smell of the alodine baths, but mostly, I remember the impact of the mighty drop hammers. Such things do not record for posterity, except in the mind. What it was like to work there doesn't get recorded at all. They still make aircraft there, and it's still Canadian, unlike CBAF which makes cars for the Indian company, Tata.
Ta ta.
