This headline is pretty misleading, to me at least. "Bottom 80%" implies the poorer 80% of Americans, but it is actually referring to the bottom 80% strictly in terms of (apparent) savings.<p>> Personal Income isn’t the only source of household assets. The two big missing pieces are holding (capital) gains on assets, and borrowing (which adds both assets and liabilities, in equal amounts, to household balance sheets). Adding these two additional measures does shift most bottom quintiles from spending deficits to asset surpluses in most years.<p>> While many have suggested that borrowing is what explains households’ ability to keep spending (it is, some), overwhelmingly it’s holding gains that “fund” the perennial dissaving of the bottom 80%.<p>So this is actually mostly explained by richer people who have significant investments in addition to their normal income.<p>Edit: The BEA says Personal Income "does not include realized or unrealized capital gains or losses." So if you sell stocks, a house, pull money out of a 401k, none of that is included in Personal Income.<p>Also, I think like ~20% of Americans are retired? Presumably most of them would be considered dissavers here, except for those who retired with almost no savings and are living solely on Social Security.
