A 45% gap persists between first-generation university graduates and those from university-educated families in reaching the top income quintile. This social fracture runs through 20 OECD countries despite three decades of university mass expansion.
Universities face their greatest paradox: just as they finally open to working-class populations, they lose their capacity to transform their social destiny. While access widens, the salary premium erodes for those who needed it most.
The Key Points
- In 20 OECD countries, students whose parents did not attend university remain 45% less likely to reach the top income quintile than those whose parents hold degrees
- The salary premium for degrees has significantly diminished for these first-generation students
- Ireland and continental systems investing in vocational training achieve better results than the United Kingdom and the United States
- University mass expansion works for access but fails at income redistribution
Mass Expansion Works but No Longer Redistributes
Access to higher education has tripled over thirty years in developed countries. In France, 47% of a generation obtains a higher education degree compared to 15% in 1990. In the United Kingdom, this proportion reaches 52%. Children of manual workers now represent 13% of British university students compared to 6% in 1960.
This democratization of access masks a more complex reality. According to the Degrees of Difference report from the Sutton Trust and the University of Oxford, first-generation graduates face a persistent 45% disadvantage in reaching the top 20% of incomes compared to children of degree holders.
The gap widens even among graduates of prestigious universities. At Oxford and Cambridge, students from non-degree-holding families earn significantly less at age 30 than their classmates whose parents hold university degrees.
This fracture reveals the limits of academic meritocracy as a tool for social redistribution. Universities produce degrees en masse but no longer correct initial inequalities.
The Salary Premium Erodes for the Most Vulnerable
The economic value of a degree erodes particularly for new entrants to higher education. In the United States, the salary premium for higher education graduates compared to those with only secondary diplomas fell from 84% in 2000 to 76% in 2024 according to the Federal Reserve Banks.
This erosion disproportionately affects first-generation graduates. In Germany, the pay gap between graduates according to social origin has widened notably in recent years, according to the Federal Institute for Vocational Training.
The phenomenon is explained by saturation of the qualified labor market. When 50% of a generation holds a university degree, it mechanically loses its rarity and its power of social distinction. Employers raise their requirements: a position that required a bachelor’s degree in 2000 now demands a master’s degree.
This diploma inflation particularly penalizes graduates without family networks. Holding the same piece of paper but not the same social codes, they struggle to leverage their qualifications when facing recruiters who prioritize signals of social class.
Professional Systems Prove More Resilient
Ireland partly escapes this spiral. Despite strong university mass expansion, the gap in social mobility between graduates according to family origin remains at 28%, seventeen points below the OECD average.
The Irish secret lies in a balanced dual system. Only 35% of young Irish students pursue long university studies. The remaining 65% pursue short vocational training directly connected to local economic needs. This strategy preserves the value of the university degree while offering concrete opportunities for alternative training.
Germany and Switzerland follow similar logic. With their developed apprenticeship systems, these countries maintain social mobility gaps of 31% and 29% respectively. Vocational training there retains a social prestige that limits the race for university degrees.
Conversely, the United Kingdom and the United States suffer the effects of their pure mass expansion strategy. These countries bet exclusively on university expansion without developing credible professional alternatives. Result: 60% of young Americans pursue university, creating massive overqualification that devalues degrees.
Social Origin Reasserts Itself After University
Data reveals that universities equalize competencies but not professional destinies. First-generation graduates obtain grades similar to their classmates from degree-holding families. They master the same technical knowledge.
Yet their trajectories diverge immediately upon labor market entry. In Canada, 43% of graduates whose parents did not pursue higher education hold underqualified jobs five years after obtaining their degrees, compared to 28% of children of degree holders.
This difference is explained by subtle mechanisms. University heirs benefit from family networks that facilitate access to valued internships and first qualified jobs. They master recruitment codes: salary negotiation, self-presentation, implicit understanding of managerial expectations.
Universities transmit academic knowledge but do not correct these social capital inequalities. They train competent technicians without giving them the keys to social advancement. This structural limit explains why university mass expansion has not reduced income inequalities as hoped.
Lifelong Learning Redistributes the Cards
Facing these limits, some countries are experimenting with alternative approaches. Finland is developing a continuous training system that allows adults aged 25-45 to resume short studies directly funded by their employers.
This strategy avoids the pitfall of juvenile mass expansion. By deferring part of the qualification effort to adulthood, it allows better alignment between training and employment and preserves degree value.
Singapore takes this logic further with its SkillsFuture system. Each citizen has a training account that allows them to retrain at any point in their career. This flexible approach gradually replaces the traditional model of a single degree obtained at age 22.
These innovations question the traditional university model. Rather than massifying initial access, they spread the training effort across the entire working life. This strategy could reconcile democratization of access with preservation of the redistributive power of qualifications.
Toward a New Division Between University and Vocational Training
Universities retain their relevance for training the intellectual and technical elites that the economy needs. But their all-encompassing expansion dilutes their redistributive capacity without improving overall economic efficiency.
Countries that best maintain social mobility combine selective universities and valued vocational training. This dual strategy preserves academic excellence while offering multiple paths to social advancement.
The challenge for the coming years will be to redefine this boundary. Neither university elitism before 1980 nor current undifferentiated mass expansion allows simultaneous optimization of economic efficiency and social justice. Teachers are redefining their profession with generative AI rather than suffering it illustrates how education adapts to technological transformations. Higher education must undergo a similar mutation in the face of democratization challenges.
The solution probably lies in revaluing short training courses and increasing personalization of educational pathways. The goal is no longer to get everyone into university, but to enable each person to find the qualification route that optimizes their chances for social advancement.
