> pretty consistently improved

I can accept the premise that condiitions have improved, but not that it was consistent. It seems to me that it was anything but; more like extremely spiky. great depression, postwar economic miracle. Massive labor movements rose and fell, general strikes... Plus most countries have had several wars + revolutions in the last 200 years, including two world wars. Not all of those are to do with technology, but I also dont think technology wasnt indirectly responsible for the conditions that created some of them

Such a good comment, I would also add how much our perception of technology lifting conditions is conflated with the increased ability of governments to steer the economy to smooth things over.
