Poor decisions=poor outcomes

Why do so many folks who work low wage jobs, make such poor decisions. A friend from high school is suffering because he decided to ignore the fact that he needed a root canal 5 years ago. He thought if he just used mouth wash and brushed good it would be fine. He should have gotten it done and got a second job to pay for it. Another person I know just got fired from his crappy job because he was late to work often because his pos car was unreliable. He should have foreseen he would get fired and get a reliable car, bust ass to make extra money to pay for it. I don’t consider myself that smart but I do have common sense. Both of these situations are obvious cause and effect. Poor decisions lead to poor outcomes

I feel like these people have no chance of actually enjoying life when they’re tied up making bad decisions or dealing with the outcomes of their bad decisions.
