A medical resident worked 207 hours of overtime in a month. His case highlights Japan’s continuing problem with karoshi - death by overwork.
Most of the developed world has this problem, in fact. The only places where it is less evident are those where they receive enough immigration from developing countries.
Once the “developing world” eventually joins the “developed world” and begins to suffer the same declining birth issue, we are going to have to rethink our model of economics to accommodate for a shrinking global population of workers. The good news is that AI and automation might solve that problem for us, but we will have to see who can actually integrate these solutions responsibly, without consolidating all of the financial resources towards wealthy oligarchs who own the technology.
Even here in Canada we may run to that problem shortly. The cost of living here has gotten so high. At least everyday items weren’t bad when housing prices were but everything has gone up in the last year I’ve been seeing articles on immigrants moving back because of how expensive it is here. They got no money to send back let alone for themselves.
