Here's a whole lot more data - covering the state of the land, the skills of the populace etc: https://imgur.com/a/vb6vR5x (translated into English)

In his book Sapiens Yuval Noah Harari argues that man's worst misstep was the move to agriculture, but after some generations there was no return since the skills required had been lost.

In much the same way, the citification (Verstädterung) is probably no longer reversible, but perhaps it was 85 years ago.

Germany was roughly 50 years behind England in terms of industrial urbanisation, the horrors depicted by Engels were fresh in everybody's imagination.

But they were anti-semitic, so I guess it's a good thing we destroyed them instead of attempting to co-exist.

However it seems to me there is not a single creature on the planet that would not be better off under the, now almost extinct, Germans.
