Open entry and test the ladder

Module objectives

• Distinguish inequality from causal diagnosis.
• Measure five ladder conditions.
• Evaluate competence criteria and access barriers.
• Analyze four institutional bottlenecks.
• Design proportionate reforms with falsifiable outcome tests.

1. Define and measure an open ladder

   About 100 minutes

   • Distinguish inequality, deprivation, and mobility rather than using one as a proxy for another.
   • Operationalize the source’s five ladder conditions.
   • Evaluate competence-based selection while accounting for unequal access and bias.

2. Distinguish public safeguards from incumbent gates

   About 100 minutes

   • Analyze zoning, licensing, credential inflation, and regulatory capture as separate mechanisms.
   • Compare safety and preservation benefits with exclusion costs.
   • Design a reform that widens entry and retains necessary protections.

Apply and defend

Restore a district’s opportunity routes

A fictional district has high rents near jobs, a degree-only repair license, unpaid entry training, and a permit board dominated by existing firms. Its safety record and service demand are incompletely measured.

What to produce

• A five-rung baseline audit with missing-data requests.
• A sequenced reform package addressing at least three bottlenecks.
• A balanced evaluation plan and response to the strongest objection.

Assessment criteria

Use these criteria for self-assessment or discussion with a tutor. The site does not certify this work or assign an automatic mark to written reasoning. Award full points for convincing evidence, about half for partial support, and zero for absent or contradicted evidence; explain intermediate scores and revise after feedback.

Total available: 20 points

Diagnosis 5 points

Distinguishes descriptive inequality, barriers, and evidence of capture.

Design 5 points

Matches each intervention to a specified bottleneck and retains justified safety measures.

Inclusion 5 points

Accounts for time, money, accessibility, and nonapplicants without blaming individuals.

Evaluation 5 points

Measures entry, competence, service quality, harm, and distribution over time.

Chapter 4: The Ladder Principle

The complete opening quotation and chapter introduction establish the problem and author’s governing position; the first teaching section reconstructs the argument and separates its assumptions from evidence. Study lesson

The Governing Claim

Presents open entry as the author’s normative priority and distinguishes it from a neutral distribution statistic. Study lesson

Two moral confusions

Tests the inference from unequal outcomes to injustice and questions the blanket surveillance claim about convergence. Study lesson

Definitions: what the ladder requires

Operationalizes all five ladder conditions with distinct measures and missing-data tests. Study lesson

Mobility

Distinguishes absolute improvement, within-life movement, and relative/intergenerational rank mobility. Study lesson

Competence

Measures reliable relevant performance without treating income or credentials as perfect proxies. Study lesson

Stability

Identifies predictable rules and manageable uncertainty that make longer-term planning feasible. Study lesson

Enforceable property

Distinguishes possession from legally protected rights and actual affordability of enforcement. Study lesson

Honest trade

Connects transparent exchange, fraud protection, and predictable remedies to access. Study lesson

Meritocracy: imperfect but necessary

Preserves luck, bias, networks, and birth caveats; compares work samples and credentials with fairness safeguards. Study lesson

The ladder is removed by bottlenecks, not by philosophy

Maps linked barriers and identifies the binding constraint rather than assuming one repeal unlocks opportunity. Study lesson

Primary Example (33): Zoning limits—housing as cartel

Traces housing restrictions, commuting, and mobility while weighing real preservation and infrastructure concerns. Study lesson

Primary Example (32): Occupational licensing—jobs behind glass

Compares legal permission with proportionate safety assessment, inspection, and alternative routes. Study lesson

Primary Example (39): Credential inflation—education as gatekeeping

Distinguishes useful educational signals from expensive eligibility filters and tests replacement-network risks. Study lesson

Primary Example (41): Regulatory capture—rules written by incumbents

Requires rule-making, benefit, and outcome evidence rather than inferring capture from concentration alone. Study lesson

Inequality’s real danger: when it becomes hereditary

Explains how institutions can insulate inherited advantage and tests entry rather than condemning family background. Study lesson

The correct target: restore ladders, punish corruption

Designs sequenced reforms in housing, skills, rules, and enforcement while preserving justified protections. Study lesson

The Lesson Line

Turns the widening-entry conclusion into measured access and harm outcomes. Study lesson

Chapter 4 Notes

Flags model-dependent housing and licensing estimates and requires original-study verification. Study lesson

The "Hazlitt" Examples (Primary)

Applies all four examples in the neighborhood bottleneck audit and district assessment. Study lesson

Part II — The Moral Economy

Includes the Part II transition and Röpke quotation as a reminder that markets rely on a wider moral setting. Study lesson
