There's a big difference between acute stress and chronic stress. Life was not as stressful as you have been led to believe. Most anthropologists estimate that hunter-gatherers worked a lot less and had more leisure time than modern humans. The stress response is adaptive for dealing with short term threats in the moment, like a fight or a predator. It's not very helpful for "threats" that never go away, like debt.
