A lot of people __do__ give a shit and this is a very common conversation among blue collar workers. I've heard about it every Christmas for the past 5 years from people who don't know how to google. Mass shifting in jobs has always been a big conversation but there's just a big divide between the working class where people aren't talking together as much.
We have coal miners complaining about "big solar" taking their jobs. We have the whole "just teach to code" fiasco. We have a lot of discussions about Amazon. And I can keep going. If you think this is a "suddenly care" type of thing then you're likely in a bubble or not paying attention (a different bubble).
