Article highlights a looming issue in the US, but why open the article with an example of a high income earner living alone who is spending beyond her needs? Makes you wonder if the author has some kind of bias...
Possibly. Though these days, I wouldn't be surprised if the WSJ was A/B testing versions with different opening examples, while showing 99% of their audience the current "max. clickiness" one.
Whats the right metric to consider credit card debt bad, or degrees of badness? When looking at nations, we look at debt compared to GDP. So for individuals, it would be debt compared to income? So someone who makes 20k and has a 10k credit card debt, is in the same bucket at someone making 200k with 100k in credit card debt. But, the 100k in debt person is in more trouble than someone who makes 500k and has 200k in debt.
