Top 20% of U.S. earners account for about 58% of spending

The share is the highest on record, while the bottom 80% make up roughly 42%, the lowest proportion cited in the source.

Fact Check
The claim accurately summarizes the linked Kobeissi Letter post, which states the top 20% account for ~58% of personal spending (highest on record) and the bottom 80% ~42% (lowest on record). The underlying trend is corroborated by Moody's Analytics data reported via Briefs.co (~59% top / 41% bottom) and the WSJ (Zandi's record-high concentration estimates). Reported figures vary modestly (58-63%) depending on the time window and series, but the claim's ~58%/~42% values and the 'highest/lowest on record' characterization are consistent with the cited data. Minor uncertainty remains because exact percentages differ slightly across outlets and measurement periods.
