Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Tax brackets are a standard fiscal mechanism used to establish progressive tax rates, which in turn promote income redistribution and vertical equity.

The analysis

The retrieved literature consistently discusses personal income taxes, progressivity, and equity, noting that progressive rate structures (tax brackets) are explicitly used as tools for vertical redistribution. Papers [0] and [1] directly connect tax progressivity to equity outcomes, supporting the claim.
