That is adjusted for purchasing power.
But sure, let's do disposable income instead
But this usual "ak-shually the numbers say you're better off than ever" line falls completely deaf today on nearly everyone for good reason.
I lived through the 80s & 90s as many of us did, and I remember the world of yesterday... it is absolutely true that the ability of the typical couple to secure a decent house, savings, and stability -- very often, back then, with just one income, like my dad who was by no means making a lot of money or holding advanced degrees -- has absolutely fallen off a cliff relative to that time.
These measures are very complex and can be extraordinarily misleading, particularly with averages that don't look at the distribution across ages, relative to personal debt ratios, etc. Some of it is also that the parameters of life today are built upon
much higher consumer spending, which makes the case that it is indeed somewhat self-inflicted, but at the same time the game we're running as western economies has built itself (questionably) upon that consumer spending so that it's almost as if the machine has to keep being fed by extravagant over-spending or the current market propped up by it collapses.
It's a total mess, hard to assign blame across all the layers, but today are people substantially better off in their basic living / working arrangement? I'm going to say, hell no they are not at all.
