You cherry picked a line and didn't include the rest:
> But the gains for middle‑ and lower‑income households were less than the gains for upper‑income households
And you're making claims that are only talking about income (where the evidence suggests that inequality is increasing) to suggest that people are better off.
Where is the evidence that "all income levels are doing better"?
You are not able to talk about these separately. Inequality is increasing, but everyone's incomes have also increased. That means everyone has more money to spend, but also some people have more money than others. Why is it so hard for your to understand this?
The original article is literally focusing on a single metric to make a wider point about inequality — does that mean you agree that it's not a valid way to analyse the data. Particularly if the conclusion doesn't seem to be borne out by actual studies in the area.
Certainly the higher your fiscal positioning, the better each recent decade has felt. Sure, we all have color TVs in our pockets [/s == "rich"], but can young people even afford to educate themselves in this economy?!
I know some very poor (and rich!) doctors and lawyers. Student loans and privatized healthcare are both evil within the USA — they can capture/demoralize just about any professional.
