I would just like to point out what I call "The IT bubble". We all make money here. Most of us make good money. Our social circles are filled with people making money.
Most people do not have this privilege. Below a certain threshold there is no such thing as budgeting/finances. It's just survival. You're not gonna budget because you can't save enough to do anything real with it, so you use it to make your life just a little easier. In my country (Slovenia, aka. EU member country) over 70% of people make less than the "average pay" and most of those make minimal pay.
At least here the problem isn't financial illiteracy. The problem is that they (a) make way too little to live off and (b) worker protections have eroded past any sane point.
