absolutely nothing, that was not my point. But people in the industry with that kind of experience are likely already in a spot where taking a job like that is a step back career wise, which is why it isn't surprising that they need to go as far as Latvia to find workers.

Money. They have actual experience and won’t work for minimum wage. Not saying it’s a good reason, but that was probably the logic employed here.

Children do not see difference between 40 and 90 year old. We are all the same to them.

I mentally chop adult age groups at 18, 21, 25, 40, 65, and 90. Within those groups, I don't really conceptualize any difference. Two clarifications: (1) this is talking about a single person, not a group, and (2) it's really more based on behavior than age; my grandma is in her eighties, but is so mentally sharp that I think of her in (the top end of) the 40-65 group.
