The Jobs and Growth Tax Relief Reconciliation Act of 2003 (Pub. L. 108-27, JGTRRA) cut the top long-term capital-gains rate from 20% to 15% and applied the same 15% preferential rate to qualified dividend income, reducing the historical double-tax disadvantage on equity payouts. The measure also accelerated the EGTRRA 2001 individual rate cuts and expanded bonus depreciation, comprising the second leg of the Bush 43 tax-cut program.
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.
