That's incorrect.
Similar numbers you could pull during 4.5% CDs we had just a few years ago (I still have couple of those on 10 years basis that every time I go to Bank of America, rep is trying to lure me to break it and "go have fun spend it", since obviously they don't make any money on 4.5% CD 6 years old CDs anymore).
Living in this country for a while, and comparing to my home Europe, I imagine US versus Europe to be like two party houses next to each other. One called "Europe", where admission is paid and when you get inside and everything you want cost money, up front. Music? Sure but you have to pay. Drinks - fine. pay before you drink. Etc. Eventually when you leave they will say "come back for more" and that's all. The party over there might be boring because invitees can only afford as much as they have in their pockets - not a lot. Versus US is totally different story. They welcome you without admission (just swipe your credit card), and party as much as you want to, virtually free. Music? Anything you want to just swipe your card. Drinks - sure, open a tab and you good to go! Everyone in US house has fun and colorful life goes on. Eventually you might seen US house being more fun, but surely more reckless with 18T in debt (T for Trillion). But also what I noticed is that a lifespan of someone's party in both houses eventually comes down to be their entire life!! So while normally when party house is getting closed down at 2am and everyone is forced to pay and leave, in real live living in USA, you party until you die and perhaps some of your debt is pushed toward your children, but that's all. So eventually you just don't care what will happen at 2am when the light are up. You be gone long before. And that "reckless" approach is what makes Americans don't want to safe. Eventually, there are just not enough incentive to save. Also, in Europe a person cannot bankrupt, only corporations. That makes a bit difference.
