I like self checkouts too. I am not arguing against them. It is just that these jobs going away is not helping former employees nor freeing them up. Economy is always going through changes, I am not arguing to stop progress.

> maybe jobs need to dry up in order to compel workers to move on

Nah. This is just lying to ourselves to feel better. Workers do not need to be compelled and it does not help them at all. The changes may be helping overall economy in the long run or just be irrelevant overall, but individuals on the receiving end are just not helped.
