The way I think about this is either the job is done in the most efficient way possible or I am asking everyone else to pay more for that product/service (sometimes a worse product/service) just so I can have a job.

E.g. if I was a truck driver and autonomous trucks came along that were 2/3rds the price and reduced truck related deaths by 99% obviously I couldn't, in good faith, argue that the rest of the population should pay more and have higher risk of death even to save my job and thousands of others. Though somehow this is a serious argument in many quarters (and accounts for lots of government spending).
