Episode: Highway Signs and Prison Labor
Host: Zachary Crockett
Produced by: Freakonomics Radio + Stitcher

Introduction

In this compelling episode of Freakonomics Radio's special series, "Economics of Everyday Things," host Zachary Crockett delves into the intricate world of highway sign manufacturing and the pervasive role of prison labor in this seemingly mundane industry. Through on-the-ground reporting in Bunn, North Carolina, Crockett uncovers the hidden economic decisions, historical contexts, and ethical dilemmas that shape the production of the highway signs we see every day.

Manufacturing Highway Signs in Bunn, North Carolina

Bunn, a modest town with a population of fewer than 330, houses North Carolina's primary highway sign manufacturing plant. Managed by Lee Blackman, the facility operates behind secured gates, producing a vast array of road signs essential for traffic management across American highways.

Key Operations:

• Production Processes: Workers shear aluminum panels, apply green adhesive sheets, and meticulously space letters to craft signs ranging from stop signs to extensive guide signs.
• Scale of Production: The plant is responsible for millions of highway signs, ensuring consistency and reliability in road signage nationwide.

Notable Quote:
Lee Blackman [02:36]: "This sign right here is 12 foot tall. This is going somewhere on Interstate 95 in North Carolina."

The Economics and Design Standards of Highway Signs

Behind every sign lies a complex web of economic decisions and regulatory standards aimed at ensuring uniformity and effectiveness.

Manual on Uniform Traffic Control Devices (MUTCD):
Established in the 1930s and currently managed by the Federal Highway Administration, the MUTCD is a comprehensive 1,200-page manual that standardizes over 500 types of traffic signs, markings, and signals across the United States.

Design Considerations:

• Typeface and Spacing: Utilizing the specialized "highway gothic" font with increased letter spacing for legibility at high speeds.
• Color Selection: Green was chosen in the 1950s for its superior retroreflectivity, enhancing visibility under headlights.
• Size and Shape: Specific dimensions ensure recognizability and consistency, such as the octagonal shape for stop signs.

Notable Quotes:
Gene Hawkins [07:36]: "The spacing between the letters in the highway Alphabet is much greater than the spacing between letters on a printed page for reading."
Gene Hawkins [16:54]: "It's not a whole lot of leeway."

The Role of Prison Labor in Highway Sign Manufacturing

The Bunn sign plant operates within the Franklin Correctional Center, a medium-security prison staffed predominantly by incarcerated individuals. This integration allows the state to manufacture signs at significantly reduced costs.

Economic Advantages:

• Cost Efficiency: Labor costs are drastically lower, with prisoners earning between 13 cents to 52 cents per hour, compared to an average labor cost of 25-35% in typical businesses.
• Revenue Generation: Service signs featuring corporate logos serve as advertisements, providing an additional revenue stream for the state.

Operational Insights:

• Production Oversight: Renee Roach of the North Carolina Department of Transportation manages the placement and maintenance of signs, ensuring they meet stringent quality standards.
• Manufacturing Process: From blueprinting to final assembly, the production of a single large highway sign can take up to 12 hours, involving precise craftsmanship by inmate workers.

Notable Quotes:
Renee Roach [12:30]: "We want to make sure that we get a good quality product because we want it out there for 20 years. We've got to be good stewards of the taxpayers money."
Lee Blackman [16:42]: "These letters can only be off an eighth of an inch."

Impact and Implications of Prison Labor in Production

Ethical Considerations:

• Labor Classification: Prisoners are classified as non-market workers, exempting employers from adhering to minimum wage laws and standard employment protections.
• Voluntary vs. Coercive: While prison programs often portray employment as voluntary, in reality, participation can be pressured, with disciplinary actions looming for refusals.

Benefits and Drawbacks:

• State Savings: Correction Enterprises, the entity overseeing prison-run manufacturing, reported $121 million in sales with minimal labor costs, passing substantial savings onto taxpayers.
• Limited Worker Protections: Inmates lack access to workplace safety regulations and workers' compensation, raising concerns about the exploitation of vulnerable populations.
• Recidivism and Skill Development: Although intended to equip prisoners with marketable skills to reduce reoffending, evidence remains mixed. Many released individuals still face significant employment barriers.

Personal Accounts:
Brian Scott [21:08]: "Get my thoughts together, get down and then get my hygiene together."
Christopher Barnes [21:45]: "We made report cards there for high schools and colleges."

Notable Quotes:
Laura Appleman [28:36]: "Prison labor is classified as non market work, so you don't have to pay them anything near the minimum wage."
Lee Blackman [28:18]: "If you pay taxes, and I'm a taxpayer in the state of North Carolina, I want everybody to be as frugal with my tax dollars as they can be."

Conclusion

The episode intricately weaves the economic efficiencies achieved through prison labor with the broader ethical and social implications of such practices. While the use of incarcerated individuals in manufacturing highway signs results in significant cost savings for state governments and contributes to sustaining an extensive network of road signage, it simultaneously raises critical questions about labor rights, exploitation, and the true benefits for the incarcerated workforce.

Through firsthand accounts and expert insights, Zachary Crockett presents a nuanced exploration of how a commonplace object like a highway sign is embedded within a complex interplay of economic strategies and social policies. This investigation not only sheds light on the hidden mechanisms behind everyday infrastructure but also invites listeners to reflect on the broader societal values and consequences of utilizing prison labor in essential industries.

Final Reflection:
As Stephen Dubner aptly summarizes, understanding the hidden side of everyday things like highway signs encourages us to question and appreciate the intricate systems that underpin our daily lives, prompting informed discussions about ethics, economics, and social justice.
