While human lifespans have steadily increased over the last century, a parallel trend is emerging with household goods: they’re simply not built to last like they used to.A growing body of evidence suggests a purposeful shortening of product lifecycles, from major appliances to automobiles, fueled by evolving manufacturing practices and consumer demand. this article examines the decline in product durability,the concept of “planned obsolescence,” and the economic factors driving a culture of disposability,even as peopel live longer and expect more from the products they purchase.
Your Lifespan Has Likely Increased, But Your Appliances Haven’t
A Culture of Disposability Plays a Role
1. The Lifespan of Our Goods is Shrinking
Household appliances are lasting less and less time, a trend fueled by a combination of planned obsolescence, innovation, and a shift away from repair-focused consumer habits. A Norwegian study found that washing machines now last an average of 10.6 years, down from 19.2 years, while ovens have seen their lifespan decrease from 23.6 years to 14.3 years [Smith, 2025]. This decline isn’t simply due to a “throwaway culture,” though that’s a contributing factor.
Advances in technology, coupled with relatively lower prices, also play a significant role. Innovations drive demand for newer models with updated features, and the affordability of appliances has transformed them from luxury items into mass-market commodities.
However, “planned obsolescence” – a deliberate corporate strategy to shorten a product’s lifespan – is a key element in the design and economics of modern goods, including automobiles. The difference in product longevity before and after 1980 is particularly striking.
Consider older vehicles, many of which remain roadworthy today, compared to newer models, which often experience major component failures within a decade.
Here’s a closer look:
1. Cars Before 1980 (The “Iron Age”):
* Expected Lifespan: 15-20+ years or 250,000 – 400,000+ kilometers for a well-maintained vehicle.
* Design Philosophy: “Built to Last.” Durability, repairability, and simplicity were prioritized.
* Key Characteristics:
* Chassis/Body: Thick, corrosion-resistant steel. Many models featured a body-on-frame construction, allowing for easier part replacement.
* Mechanics: Simple, naturally aspirated gasoline engines with low stress. Transmissions and differentials were exceptionally durable.
* Electronics: Minimal. Carburetors, contact ignition, basic wiring. Fewer components meant fewer potential points of failure.
* Corrosion: The primary threat to vehicle longevity. While mechanical components could last for decades, bodies were susceptible to rust.
Specific Examples:
* Volvo 240 (produced 1974-1993): Renowned for its longevity. Average lifespan exceeded 20 years, with many exceeding 500,000 kilometers.
* Mercedes-Benz W123 (produced 1976-1985): Often called “the most reliable car ever built.” Still used as taxis in Africa and the Middle East with 1-2 million kilometers on the odometer.
* Soviet / Eastern Bloc cars (Lada, Volga, Trabant): Primitive but incredibly repairable. Lifespan was limited by part quality and corrosion, but mechanically they could be maintained indefinitely.
* American Land Yachts (Cadillac, Chevrolet 70s): Large, with simple V8 engines. Now prized as collector cars due to their robustness.
2. Cars After 2000 (Especially After 2010) – The Age of “Electronics and Efficiency”:
* Expected Lifespan: Manufacturers design for 10-15 years or 200,000 – 250,000 kilometers under normal use. While vehicles may continue to function beyond this point, expensive component failures become increasingly common.
* Design Philosophy: “Built for a Limited Life.” A balance between cost, efficiency, environmental concerns, safety, and component maintenance/replacement intervals.
* Key Factors Limiting Lifespan (Planned Obsolescence and Complexity):
1. Unrepairable Electronics: Complex Engine Control Units (ECUs), sensors, and infotainment systems. A failure in a single circuit board often necessitates replacing the entire module.
2. Components with Limited Lifespans:
* Turbos (in many diesel and gasoline engines): Lifespan of approximately 150-250,000 kilometers.
* Dual-Clutch Transmissions (DSG/DCT): Complex, with limited lifespan of clutches and mechatronics.
* Hybrid Batteries: Expected lifespan of 8-12 years / 150-200,000 kilometers.
3. Lightweight Materials: Plastics and aluminum, which become brittle over time or degrade from UV exposure. Even some engine components are now made of plastic.
4. Downsizing: Small turbocharged engines operate under high load and temperature, increasing wear and tear.
5. Connectivity and Software: Software obsolescence and lack of updates can render systems inoperable.
In conclusion:
In the past (before 1980), mechanical longevity was high, and corrosion was the main enemy. If a vehicle was protected from rust, it could potentially last indefinitely, as almost anything could be repaired or fabricated.
Today (after 2010), initial reliability is high, but after a certain mileage (typically after the warranty expires), an “exponential failure curve” emerges, marked by expensive, complex, and often irreparable component failures. The economics of repair become unsustainable – a phenomenon known as total economic loss.
So, planned obsolescence is a real and measurable phenomenon in the automotive industry. It doesn’t mean a car simply “stops working” on a certain date, but rather that the cost of keeping it safe and functional after 10-15 years exceeds its market value, forcing the owner to dispose of it. Previously, the opposite was true – maintenance costs were low, and the vehicle retained its functionality for many years.
2. The Good News – Human “Warranty” Has Increased
Life expectancy, a key indicator of mortality across all age groups in a given year, reveals how long a newborn infant is expected to live on average.
Average life expectancy has increased by roughly 30 years since 1900 [Our World in Data, 2025].
In 1900, global average life expectancy was 32 years. By 2023, it had more than doubled to 73 years. Significant improvements have been made worldwide, with life expectancy increasing more than twofold in every region. This isn’t solely due to reduced infant mortality; people are living longer at all ages.
Even after World War II, there were significant declines in life expectancy due to events like the Great Chinese Famine, the HIV/AIDS epidemic in Sub-Saharan Africa, the Rwandan genocide, and the COVID-19 pandemic.
Looking at Bulgaria, in 1990, Bulgarians lived an average of 40.2 years, while the average European had two more years of life – 42.7 years, and the average global citizen – 32.0 years. By 2023, Bulgarians had an average life expectancy of 75.6 years, Europeans – 79.1 years, and people on Earth as a whole – 73.2 years.
Despite the increase in average life expectancy in Bulgaria, it remains closer to the Asian average than the European average. The disparity in wealth and income in Europe is highest in Bulgaria, a consequence of the choices made by its leaders.
