Jobs do not disappear, they just change

They can be fully automated out of existence, e.g the jobs of Herb Strewer and link-boy.

And, indeed, that old job called "computer".

You have to also take into account income not just the unemployment rate. Growth has been close to non-existent if not negative over the last 40-50 years or so if earn below the median.

In the long term, yes. But shouldn't we have some compassion for those who get screwed in the short term? The horseshoe makers who were thrown out of work at the time may not have been able to find decent new employment. We have copious modern-day examples of jobs that have been obsoleted and those who were immediately affected still haven't been able to recover.

These sorts of labor shifts can't avoid harming those who get the short end of the stick.

Saying this is not to say that such changes shouldn't happen. It's inevitable and necessary in order for society to adapt to changing conditions. But I very often see a disregard for the reality that people really do get hurt badly in these shifts.

Long-training-time jobs are the worst for this. E.g. medical

By the time you mint a professional in medical something, they've put a decade+ into training for it. And in the US model, incurred substantial debt doing so.

One reason I'm more sympathetic to the artificial medical supply/demand management shenanigans.
