The rich stole everything
Gini is a measurement of economic equality something that was improving in this country until the late 1970s where it stalled and reversed beginning a four decade period where equality decreased by 20%, a move that shows a statistically strong correlation with the accumulation of wealth in the form of savings (which makes sense as savings are extra money not needed to live).
Inflation has grown those savings from $348B in 1975 preceding peak equality by three years to $10.6T when the series collection was halted in 2020.
Absolute cause and effect is impossible to determine, but it's pretty clear that a small group of people has accumulated more wealth at a much faster pace then the rest of the people.
