Progressivity of the personal income tax schedule, including top marginal rates, bracket spread, and targeted credits (EITC-equivalents).
Chancellor Nigel Lawson's 1988 Budget delivered the most dramatic income-tax restructuring of the Thatcher era: the basic rate fell from 27% to 25%, all higher rates collapsed into a single 40% top rate (replacing the previous 40%/45%/50%/55%/60% schedule), and the rate threshold was sharply reduced. The reform completed a decade-long fall from 1979's 83% top marginal rate and substantially flattened the UK income-tax structure.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
