Norwegian here. 7.5 hour work day, lunch included. We don't get paid as much as US software engineers, though. We are "salaried" in the sense that we have a fixed salary, but we also have strong protections in law that require companies to pay if they require more than 8 hours per day from an individual employee. I think your question is pretty obvious; as long as salaried means "fixed price to squeeze out as much effort as possible" then obviously a large portion of profit-focused companies will do just (misguided or not; organizations are rarely super insightful in aggregate) that in the absence of legislation that discourages it.
