There's a large difference between being able to and choosing to save that much. I didn't say that it was the norm, but it's certainly possible if you have a near-median salary. Not doing so is a choice if you make a reasonably good salary, albeit an extremely common one that most people don't make consciously. It requires consciously tracking your spending, and being willing to forgo or at least cut back on some of the luxuries that have become much more common in the US and presumably Europe in the past 30 years (like eating out frequently). In return, you can get better financial security, even without an astronomical salary.
