The Dearth of Common Sense in Modern Economics (And Why It Matters)

The Dearth of Common Sense in Modern Economics (And Why It Matters)

You’ve felt it. That weird, hollow sensation when you walk into a grocery store and see shelves that are technically "full" but somehow missing everything you actually need. Or maybe you've noticed it in the job market, where there’s a massive dearth of qualified applicants for high-tech roles despite universities churning out graduates at record rates. We use the word to describe a lack, a scarcity, or a famine. But honestly? It’s more than just being "out of stock."

A dearth is a structural failure. It’s the gap between what we expect and what reality actually delivers.

Take the current state of global logistics. We aren't just talking about a few missing microchips. We are looking at a systemic dearth of raw materials that has trickled down into every single aspect of consumer life, from the price of a used Ford F-150 to the wait time for a new dishwasher. It’s frustrating. It's expensive. And it’s mostly because we built a "just-in-time" world that has zero margin for error.

The Difference Between Scarcity and a Real Dearth

People mix these up constantly. Scarcity is a fundamental economic fact; there is a finite amount of gold in the earth’s crust. You can’t just wish more into existence. But a dearth? That’s often a timing or distribution nightmare. It’s the absence of something that should be there but isn't.

Think about the Great Famine in Ireland. Historians like Cecil Woodham-Smith have pointed out that while the potato crop failed—a literal dearth of food—Ireland was actually exporting grain and livestock at the same time. The "lack" wasn't total; it was a lack of access. It was a failure of policy.

Today, we see this in the "dearth of housing" across major metros like San Francisco or London. It isn't that we've run out of wood or nails. We have a dearth of permitted land and a dearth of willpower to build upward. We’re essentially starving in a land of plenty because the rules don't allow the food to reach the table.

Why Quality Talent is Vanishing

If you talk to any CEO right now, they’ll give you the same earful. They aren't complaining about a lack of people. They’re complaining about a dearth of specific, high-level skills. This isn't just "nobody wants to work anymore" rhetoric; it’s backed by data from firms like Korn Ferry, which suggests that by 2030, the global talent shortage could reach 85 million people.

That is a staggering number.

We have a massive oversupply of generalists and a frightening dearth of specialized technicians, nurses, and engineers. It’s a mismatch. Basically, we’re training people for the 20th-century economy while the 21st century is screaming for something else entirely. It creates this weird paradox where unemployment can exist alongside a desperate need for labor.

The Psychological Toll of Living with Less

Living through a period of dearth changes how your brain works. Sendhil Mullainathan and Eldar Shafir wrote a brilliant book called Scarcity: Why Having Too Little Means So Much. They found that when people experience a dearth of something—whether it’s time, money, or social connection—it creates "tunneling."

You lose the ability to think long-term. You get so focused on the immediate lack that your IQ effectively drops. Your "bandwidth" is consumed by the struggle.

  • It makes you impulsive.
  • It makes you prioritize the "now" over the "later."
  • It creates a cycle of poverty that is nearly impossible to break because the mental cost of the dearth is so high.

Honestly, this applies to our digital lives too. There is a profound dearth of deep attention. We are constantly pinged, poked, and prompted. We have an abundance of information but a total dearth of wisdom. You can scroll for four hours and come away knowing less than when you started. That’s a scarcity of meaning in an ocean of content.

The Environmental Reality

We have to talk about water. In the American West, the dearth of Colorado River water isn't a "maybe" anymore—it's a "when." We are seeing Lake Mead and Lake Powell hit "dead pool" levels where they can't even spin the turbines for power.

This isn't just a drought. A drought is temporary. A dearth of water in an arid region being over-farmed is a permanent shift in the baseline. We’re essentially trying to write checks from a bank account that has been overdrawn for twenty years.

Agriculture uses about 80% of that water. When the dearth hits the farms, it hits your grocery bill. It’s all connected. You can’t have a dearth of water without eventually having a dearth of affordable lettuce, alfalfa, and beef.

Historical Lessons on Surviving the Lean Times

History is basically just a series of humans reacting to a dearth of resources. The Bronze Age Collapse? Likely triggered by a dearth of tin, which was needed to make—you guessed it—bronze. Without that one specific ingredient, entire empires in the Mediterranean just... folded.

It's a warning.

Our modern supply chains are even more fragile. We rely on a handful of factories in Taiwan for chips and a few mines in Africa for cobalt. If there is a dearth of stability in those specific spots, the entire global economy catches a cold.

The most successful societies aren't the ones that never face a dearth. They are the ones that build in redundancy. They have "slack."

Moving Toward a Surplus Mindset

So, how do you actually deal with a dearth in your own life or business? You can't just wish for more. You have to change the system.

If you're a business owner facing a dearth of talent, you stop looking for the "perfect" candidate who doesn't exist. You build an internal training program. You manufacture your own talent.

If you’re a consumer facing a dearth of affordable goods, you shift toward durability. You buy the thing that lasts ten years instead of the thing that lasts ten months. It’s about reducing your dependence on a fragile system.

Actionable Steps for Navigating Scarcity:

1. Audit your dependencies. Look at your life or your business. If one specific thing disappeared tomorrow—a vendor, a specific software, a certain type of food—would you be totally stuck? Identify where you are most vulnerable to a dearth and find a backup.

2. Invest in "Slack." In an efficient world, slack is seen as waste. In a resilient world, slack is survival. Keep a little extra cash, a little extra inventory, or a little extra time in your schedule.

3. Focus on Skills, Not Credentials. The dearth of talent is largely a dearth of practical ability. Don't just collect degrees; collect "stackable" skills that are hard to automate.

4. Practice Mental Conservation. Recognize when "tunneling" is happening to you. If you’re stressed about a lack of money or time, stop making big decisions. Your brain isn't at its best when it's operating under a dearth of bandwidth.

The world isn't going to get less volatile. If anything, the dearth of predictability is the new normal. We have to get comfortable with the fact that things won't always be on the shelf when we want them. The goal isn't to eliminate the lack—it's to make sure the lack doesn't break you.

Build systems that don't require perfection. Because perfection is the one thing we’ll always have a dearth of.
