Following the 29 Jun 1987 democratisation declaration and Labour Union Law amendments, Korean workers gained effective rights to organise — unionisation surged from 1,137 unions (1986) to 7,883 (1989); strikes exploded from 276 (1986) to 3,749 (1987); nominal wage growth averaged 18-21% annually 1988-1991. Real wages tripled over the decade, fundamentally altering Korean manufacturing cost structure and driving industrial upgrading toward capital/technology- intensive sectors.
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.
