The importance of "The Economy" doing well is baked deep into the American psyche: if the economy is healthy, the country is healthy. And "doing well" is understood to mean businesses are healthy (revenue/market/profit growth). That means working as much as possible, for as few benefits as possible, is the accepted standard. Because who wants the economy (and by implication, the country) to do poorly? And if some, or a lot, of people suffer from stress and mental breakdowns, physical injuries, or death, well, that's a price our business and political "leadership" is willing to pay. (Some sarcasm there, in case it isn't obvious.)
Recently there does appear to be more noise around employee/worker benefits (including wages), hence things like the striking screen actors and auto workers (and attempted strike from railroad workers, who have shockingly terrible benefits), and renewed interest in unions.
The health of a country ought not be measured solely by its GDP and financial markets.
