I agree they’ve been trying to mitigate this but as I understand it things are quite precarious regardless. It’s not always possible to mitigate a disaster you see coming even if you try your best to prepare for it.
There has been more talk of it since then - that article just was the only concrete & most reputable source I could think of at the time and I didn’t want to turn a post into a research project.
Anyway, while there is more awareness of the issue it is, more or less, the same shady greed-driven risky behavior and nonsense that happened with home mortgages except its commercial mortgages and they’ve seen it coming.
