Correct, and I am saying the Luddites were a group of people that suffered mass unemployment following a technological change. Specifically, the luddites were a group of 19th century textile workers that were left out of work due to the introduction of automated machinery in the textile industry. In other words, they are a perfect example of what GP claims hasn’t happened.

A small group is not "mass unemployment" -- that's the point.

The "never rose above a couple of thousand" small group refers to the number of activist Luddites. It doesn't refer to the people working in the textile industry in general - which was a big group, and which was heavily affected.

Even "all textile workers" was never a large fraction of "all workers."
