Earlier quoted context omitted.
A version of this comment appears every time this is discussed. This isn’t what we’re talking about. These aren’t liquidity problems. People really just don’t have the money.
It's literally what the article is talking about. I included the quote. I suggest they are misinterpreting their data, and are measuring the wrong things. It's like that daft statistic a few years back that 40% of corporations don't pay any income tax. This raised all sorts of righteous hysteria. Never mind that 40% of corporations lost money that year, and income taxes are not due when you lose money.
I think I know what it's saying (probably because I have a lot of experience with the type of people I'm imagining) and you guys think you know it's saying something else (because of your own experiences having money that's inaccessible), but, ultimately, the question is too imprecise for either of our claims.
So, yes, I strongly suspect I'm right -- "selling something" is pretty plainly not referring to financial instruments -- but it's true that it's more intuition than fact.
