It's actually almost certainly true just on the basis of basic numbers. Many people who are really actually quite poor (making say under $35k CAD annually for a family of 5) manage to make ends meet and even save a little. So if you make more than this but can't save any it's because you're spending on things they are not and which are therefore nonessential.

Now maybe restaurant food, name brand groceries, driving two SUVs, vacations, etc etc whatever it is for a given person are seen as essential. That's how lifestyle works after all and we often can't imagine our lives without it. So I'm not saying it's a "simple" matter of just spend less because it's often not very simple feeling. But from a numbers PoV it is possible for most people who otherwise see themselves as struggling in theory.
