Ease of hiring/firing, collective-bargaining scope, minimum wage rigidity, temporary/permanent contract regulation.

The Prélèvement forfaitaire unique (PFU), introduced in the 2018 finance law, applied a flat 30% levy (12.8% income tax plus 17.2% social contributions) on dividend, interest, and capital-gains income, replacing the prior progressive schedule that could exceed 60% at the margin. The flat tax aimed to simplify capital taxation and align France's effective rate on portfolio income with peer European jurisdictions, reducing dispersion across asset classes.
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.
