Even in finance, the phenomenon of working crazy hours didn't end with the 80s. I'd be shocked if it wasn't still the norm there.
In the medical field, it's quite typical for doctors and nurses to work insanely long shifts and get by on very little sleep... this was the case even before the pandemic hit, but as everyone knows it's gotten even worse since as doctors and nurses started getting sick, dying, and quitting, leaving more work for the rest.
It's long been common in the tech field.. especially in startups, but even among established firms working long hours is quite common.
All sorts of people living paycheck to paycheck and undocumented workers are routinely exploited, and working long hours is common there too.
In many parts of the world it is the fortunate minority who can afford to have a healthy work-life balance and get enough sleep.
