Contemporary high-trust welfare states face a paradox: despite historically unprecedented levels offormal inclusion, significant population segments report exclusion, eroding institutional trust, andalienation from mainstream society. This article proposes theperceptual legitimacy gap(PLG) —the divergence between objective structural inclusion and subjective experience of position — as aunifying explanatory mechanism. Drawing on a comparative meta-synthesis across four analyticallevels (macro-temporal, institutional legitimacy, systemic coherence, subjective exclusion), weintegrate legitimation theory (Beetham), recognition theory (Honneth), welfare state typologies(Esping-Andersen), and social acceleration theory (Rosa) into a multi-level model of coherence loss.The model specifies three structural locations where legitimacy gaps arise — the delivery gap (G1),the recognition gap (G2), and the comparison gap (G3) — and a multiplicative threshold condition(D×N×C) under which latent divergence transitions to structural fragmentation through parallelnormative orders. We argue that perceived exclusion arises not primarily from material deprivationbut from recognition deficits amplified by shifting comparison horizons, institutional over-distance,and friction reduction in late-modern societies. Swedish empirical data (SOM 1986–2024, BRÅNTU 2007–2025, Eurostat) are used to illustrate and test the model’s predictions. The modelgenerates falsifiable predictions: that social-democratic regimes will exhibit the highest relativePLG, that legitimacy erosion will be strongest where universalist rhetoric meets perceived selectiveenforcement, and that threshold conditions for structural fragmentation require the simultaneouspresence of persistent divergence, narrative density, and coercive-only response. Implicationsfor policy, institutional design, and future research — including an operationalizable PerceptualLegitimacy Gap Index (PLGI) — are discussed.Keywords:perceptual legitimacy gap, recognition, coherence, welfare state, perceived exclusion,parallel orders, institutional trust, social acceleration
