It's not a bad analogy, just that the reason you borrowed matters because it reveals whether you have options on spending or consumption side to get back to balance.

If I borrowed a lot, because I decided to take vacation, should I go back to work or stop eating?

I mean, I like joking around as much as the next Twitter troll, but isn't there anything sacred anymore?

Sorry, not a macroeconomist - it's industry and technology (so, time) specific, and quite different in short vs long term.

On this one: retained earnings in A-S play a major role relative to P-S, but not as much relative to P-S-Z - they do a similar imputation. In particular, you can still see in both a similar discrete (though smaller than in P-S) jump after 1986
