Nah, the capitalists will continue to outsource what labour they can to cheaper countries. It's just the jobs that have to be done here that will be understaffed and overworked. Things like maintenance of infrastructure, public services, medical care... You know, stuff the capitalists don't actually depend on, because the things they need will take priority. Your internet may get worse and more expensive, but expensive isn't an issue for them and they'll just pay extra for premium treatment. Public healthcare might die, private healthcare might suffer too, but they'll just invent premium healthcare for themselves.
Hence all the talk of raising the working hours per week, raising the pension age, cutting unemployment benefits to force people to accept work even at worse conditions... At some point, even the pay can't save you from burnout, and ultimately you need the job just as much, so your leverage won't nearly be as strong. Hell, who knows, maybe Strike Busting will become a whole service industry of desperate suckers.
It might reach a point of collapse, who knows. Maybe they'll see it coming and make concessions to avoid it, but they'll be the bare minimum.
Maybe they won't, and will simply be the last to suffer, but that's hardly any consolation for the rest of us.
Or maybe they're already planning for how to take advantage of the chaos and undo a few centuries of civil progress to force us all back into serfdom.
