> worker shortage is the main reason why self-checkout became popular here in Europe at least
What exactly do you mean?
That the companies moved to self checkout because they couldn't get the staff?
Or people prefer self checkout because the manned tills are few in number?
The first is very very hard to believe
>The first is very very hard to believe
Why?
At least in the US our unemployment rates have been very low. Higher demand for labor leads to higher labor costs which allows more expensive automation to be economical.
You can say "Well pay them more", but that doesn't get you out of a labor shortage. That just ensures you get the labor rather than someone else.
