When an additional qualification improves one applicant's chances of employment, it is tempting to infer that giving everyone the qualification will improve everyone's chances by the same amount. The inference overlooks a distinction between increasing productive capacity and improving relative position. Education can do both, but their social consequences differ. A skill may enable tasks that were previously impossible; a credential may also help an employer choose among candidates for a fixed number of positions. The private return to moving forward in a queue does not reveal how much the queue's destination has expanded.
This distinction does not reduce education to signalling. Learning can develop understanding, judgement, technical competence, and forms of participation whose value exceeds employment. Nor does it imply that a credential conveys no useful information. Employers often face uncertainty about applicants' abilities and may use qualifications as imperfect indicators. The analytical problem is to identify which mechanism explains a particular advantage. If the qualification primarily develops scarce competence, wider access can enlarge productive possibilities. If it primarily differentiates candidates whose competence is otherwise similar, universal acquisition may shift the threshold without reproducing the original advantage for everyone.
Imagine a hypothetical office that once required a basic certificate but now receives applications from many graduates. It may begin using a degree as an initial filter even when the work has changed little. Applicants then have reason to obtain degrees because failing to do so excludes them from consideration. Their individual decisions can be rational while the resulting escalation produces limited improvement in the task itself. This form of credentialism produces credential inflation: the entry requirement rises partly because the supply of credentials has changed. The qualification becomes necessary through competition, not solely through a corresponding transformation of occupational demands.
The cost of escalation is uneven. Families with resources can finance additional years of study, unpaid experience, and supplementary certificates. Others may possess relevant ability but be unable to sustain the sequence of requirements through which ability becomes institutionally visible. The labour market then appears to reward educational achievement while also sorting by the capacity to finance its recognised forms. This does not mean every successful applicant lacks merit. It means the procedure through which merit is identified can incorporate advantages that are not themselves evidence of competence. Selection criteria require evaluation as mechanisms, not merely admiration as accomplishments.
An employer might reply that credentials reduce screening costs and correlate with desirable traits such as persistence. That argument can be practically serious without settling the social question. A rule efficient for one employer can impose substantial costs on applicants and on the wider educational system. If each organisation externalises screening costs onto candidates, the aggregate burden may grow even while each hiring department becomes more efficient. The relevant accounting unit changes the verdict. A low-cost decision for the firm may depend on years of costly preparation undertaken by people competing for opportunities that remain scarce.
The concept of a positional good clarifies the mechanism. Some benefits depend partly on relative standing rather than only on absolute possession. A qualification can have intrinsic educational value and positional labour-market value simultaneously. Expanding access may improve the first while reducing the scarcity that sustains the second. Disappointment can therefore coexist with genuine educational progress. Graduates may know more than earlier cohorts yet encounter weaker employment advantages because the comparison group has also changed. Treating their frustration as proof that education has become worthless mistakes the erosion of one return for the disappearance of every return.
Conversely, celebrating higher attainment without examining employment can conceal a real mismatch. If institutions market a credential principally through its occupational promise, they cannot evade scrutiny by invoking broad personal enrichment when the promise fails. Different claims create different obligations. An educational programme may be worthwhile for civic or intellectual reasons, but applicants deserve clarity about the basis on which they are encouraged to invest. The defence of education becomes more credible when its multiple purposes are distinguished rather than moved opportunistically into whichever category is hardest to evaluate at the moment of criticism.
Alternative assessments can reduce some dependence on credentials, but they introduce their own problems. Work samples, apprenticeships, and practical tests may reveal relevant competence more directly. They can also be costly, vulnerable to coaching, or inaccessible to applicants who cannot afford unpaid participation. A supposedly neutral test may reward prior exposure to the exact task format. Replacing one signal with another does not abolish selection or inequality. The question is whether the new procedure better represents the required ability, reduces unnecessary barriers, and allows candidates to demonstrate competence through more than one narrow route.
Institutions also influence the scarcity they later treat as inevitable. The number of desirable jobs depends on investment, organisational choices, demand, and the distribution of work, not only on the supply of qualified applicants. A policy focused exclusively on improving employability can imply that unemployment is principally a defect in individuals even when opportunities are insufficient. This implication is analytically unwarranted. Training can improve a person's prospects and still fail to solve an aggregate shortage of suitable work. An intervention at one level should not be credited with resolving a problem whose mechanism operates partly at another.
There is nevertheless a danger in using positional competition to justify limiting educational access. Exclusion would preserve scarcity for those already admitted while denying others the intrinsic and practical benefits of learning. The fact that universal access changes a credential's market value is not an argument for retaining privilege. It is an argument for reassessing how education, selection, and employment are connected. A society can broaden learning while reducing unnecessary credential requirements and improving routes into competent work. The goal is to prevent access from becoming an endless race whose finish line moves whenever more people approach it.
The debate also concerns what students learn to value. If every course is treated as a badge in a competitive portfolio, the incentive to explore difficult ideas can be displaced by the incentive to accumulate recognisable achievements. Institutions may respond by producing more certificates rather than deeper learning because the former are easier to display. This is not an inevitable consequence of ambition. It is a response to the signals through which ambition is rewarded. Changing assessment and recruitment practices can therefore affect the educational experience itself, not merely the distribution of jobs after education ends.
The education that moves the queue should thus be assessed alongside the education that enlarges capability. Both are real, but they cannot be assumed to produce identical public benefits. Individual advice to acquire a credential may remain sensible even when collective reform would reduce dependence on that credential. Recognising this tension prevents moralising about applicants who respond rationally to existing rules. The more demanding question is whether those rules convert educational effort into meaningful capacity and opportunity. A society has not solved its problem merely because everyone runs faster if the principal achievement is to preserve the order of arrival.
