The graph is truly awful for showing hours worked. Also, what's that gigantic leap in disposable income? Are we to believe that on average American's have $50,000 worth of disposable income when they didn't before? I think that relies heavily on which version of average is being discussed.
the spike in the last year is an glitch in their display software, but it doesn't change the central point of what's being shown here. What version of average do you think is appropriate?
Even here there is a definitive and deliberate bump right during the beginning of the COVID times. I don't believe that's an artifact. Somehow this analysis is saying people are vastly better in August than they were in February.
I think that "average" in most of the different versions is useless. The millionaire and billionaire classes can be so over-represented they can draw the rest up. It doesn't answer if all of society is actually becoming more well off or just the cream continuing to rise.
In this case it would seem that that money is less "disposable" and more "extremely import to ration". I must not understand the definition of disposable.
