edit: deleted this chunk of my argument because as pointed out by dweekly Pew Research are already comparing in 2018 dollars. What matters is that U.S. middle-income share of aggregate income fell from 62% to 43% – is this not the usual measurement? This is what people mean by "the middle class is shrinking". It doesn't matter if the average middle-income has increased, what matters in this context is the overall purchasing power of the middle class. Even adjusted for so-called inflation you have to wonder does your 2018 $ go as far as your 1970 $ ? How would we measure that? How about we look at household debt? According to this site “In 1983, the top 5 percent had 80 cents of debt for every dollar of income, while the remaining 95 percent had 60 cents for every dollar. By 2007, after decades in which an increasing share of income flowed to the top, the situation had reversed. The top 5 percent had 65 cents of debt for every dollar of income, while the remaining 95 percent had $1.40 in debt for every dollar. The situation remains skewed today.” https://tcf.org/content/commentary/graph-household-debt-and-middle-class-stagnation/?agreed=1 https://tcf.org/content/commentary/graph-household-debt-and-... – this suggests that a $ dollar does not go as far today and that today maintain a middle-income lifestyle the average family has to go deeper into debt. ( You'll note that according to the New York Fed total household debt has ballooned from a fraction of a trillion to over fourteen trillion from the '60s to the 2010's https://www.newyorkfed.org/medialibrary/media/research/staff_reports/sr882.pdf https://www.newyorkfed.org/medialibrary/media/research/staff... )
