Your explanation doesn't explain anything away but to try and put some sort of weird blame on poorer people for borrowing, it's just as usual of a narrative as the populist thing to be infantilizing poorer people. There's however a pretty big difference between borrowing at your limit or sometimes beyond because you're trying to get through a pandemic or have a place to live, and borrowing at high risk because you're playing with huge sums and can in fact afford the loss. The latter as a group made more money during the pandemic from any possible source you could look at, the former as a group lost money and jobs. I won't insult you by throwing Oxfam reports at the situation, especially since you might be keen on calling it populist too and calling it a day.
