The Paradox of Productivity: Why We Still Work Long Hours Despite Keynes's Prediction and Technological Progress

Almost a century ago, John Maynard Keynes optimistically predicted that by 2030, technological advancements would lead to a 15-hour work week. While his foresight regarding dramatic productivity boosts proved accurate, the reality is that average work hours, particularly in the US and UK, have barely budged since the 1980s, and overall labor force participation has increased significantly due to more women entering the workforce. This episode explores the perplexing disconnect between our unprecedented ability to produce more with less human labor and our continued dedication to long working hours, questioning whether we are addicted to work, driven by consumerism, or trapped by systemic inefficiencies. A key argument is that Keynes underestimated the economy's propensity to invent new service sector jobs, many of which are perceived as having questionable value, leading to widespread feelings of meaninglessness among workers.

The podcast delves into the economic forces at play, specifically the interplay between the income effect and the substitution effect. While higher wages could theoretically allow individuals to work less (income effect), the increased opportunity cost of leisure (substitution effect) often incentivizes working more to afford new goods and services that have become part of our 'minimum standard' of living. This phenomenon, coupled with evolutionary hardwiring for work, societal valorization of long hours, and status-driven competitiveness, explains why economies have largely chosen to consume more rather than work less. The discussion also highlights the concept of 'bullshit jobs,' as defined by David Graber, which are so pointless that even the incumbents cannot justify their existence, and the widespread practice of 'productivity theatre' or 'ghost-working' stemming from the difficulty in accurately measuring individual marginal product of labor, leading to Parkinson's Law where work expands to fill available time.

In response to these inefficiencies and the prevalence of meaningless work, the four-day work week emerges as a potential solution. Recent global pilot programs, notably in the UK, have demonstrated overwhelmingly positive results: maintained or increased revenue, significant productivity gains, reduced staff turnover and sickness, and improved employee well-being and morale. These successes are attributed to the 180-100 rule (100% pay, 80% hours, 100% output), which forces the elimination of unnecessary tasks and 'bloated' activities, proving Parkinson's Law in reverse. The pilots suggest that a reduced work week can foster greater efficiency and focus, benefiting both businesses and employees.

However, the podcast also addresses the significant challenges and drawbacks of a widespread four-day work week implementation. It acknowledges that it may not suit all sectors (e.g., manufacturing, healthcare) and that a one-size-fits-all approach is unrealistic. Potential negative implications include wage depression in attractive 4DWW sectors, increased inequality between white-collar and blue-collar/key workers, and the risk of inflation if businesses need to hire more staff or pay overtime to maintain output. The self-selection bias in pilot programs means the positive results are not universally generalizable, though they warrant further exploration. Despite these hurdles, the historical trend towards shorter work weeks, coupled with accelerating automation and AI, suggests that systematic change is possible, driven by inertia and the recognition that we have solved fundamental economic scarcity but have yet to fully reap the benefits in terms of increased leisure and life satisfaction.

Almost 100 years ago, one of history's greatest economists boldly predicted that by 2030 we'd only work 15 hours a week.

Are we secretly addicted to work relying on it for pride, purpose and identity? Do we prefer consuming more than working less?

The point is although our real wages have increased so too have our minimum standards for what we consider a decent and dignified quality of life.

As Keynes himself recognised humans, like all animals, are evolutionarily hardwired to work.

Ultimately what we've seen is that as an economy we've chosen to work more and consume more rather than work less and consume less.

He defines Wainers so completely pointless that even the person who has to perform it every day cannot convince themselves that there's a good reason for them to be doing so.

Work expands to fill the time available for its completion.

The end result is that in many office environments, presence equals performance and the theatrical display of looking busy is valued more than your actual output.

If you reduce the available time, much of the bloated, unnecessary or unfocused activity simply vanishes by necessity.

We're the only era in human history to have solved economic scarcity in its most fundamental form, yet we still organise our economy and work patterns like we're fighting to survive.
