Competitive wage bidding does not self-correct income inequality
Competitive labor markets automatically reduce income inequality over time as firms bid up wages to retain workers, eliminating prolonged wage disparities without policy intervention.
OECD Gini coefficients rose in 17 of 22 member nations from 1985-2018 despite maximum market liberalization — precisely the period the self-correction mechanism should have operated most powerfully; Jacobson, LaLonde & Sullivan find displaced workers face permanent 25-30% earnings losses that markets never reverse, and Berger, Herkenhoff & Postel-Vinay find the job-switching wage premium fell from 3.5% to 1.2% between 1970 and 2015, indicating declining competitive pressure rather than self-correction.

Premise Assessment
Is the claim as stated true? Four dimensions, each 0–25, sum to 100. The verdict label is derived from this score. Full rubric →
Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
OECD data shows Gini coefficients rose in 17 of 22 nations from 1985-2018 despite market liberalization, and US bottom-50% real wage growth stalled at 0.3% annually from 1975-2015 versus 1.3% productivity growth, directly contradicting the self-correction mechanism.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
The wage-bidding mechanism assumes perfect information and costless mobility, but Berger, Herkenhoff & Postel-Vinay's finding that the job-switching wage premium fell from 3.5% to 1.2% between 1970 and 2015 shows employer monopsony power rising rather than competitive bidding equalizing wages.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Labor economists including Piketty and Stiglitz document persistent structural inequality growth despite decades of liberalization, rejecting the automatic wage-competition correction thesis.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
Jacobson, LaLonde & Sullivan's finding of permanent 25-30% earnings losses for displaced workers has been replicated by Davis & von Wachter across business cycles and skill levels, showing markets consistently fail to reverse these wage penalties.
Individual vs. Structural
