Instead of buying up people, they should invest in robotic technology.
Thats a bloody stupid suggestion. Companies are not doing it for a reason. I presume the article doesnt only relate to abattoirs like you see in the images. Mechanical engineers, plumbers, electricians...good luck trying to automate those skills.
One day they will ALL be automated. It's just a matter of time. One day, even engineering would be done by machines; it would be machines designing machines. In the article, apparently automation has already been utilized by the companies experiencing the labor shortage. Welcome to the brave new world!!
