The Everything Shortage: Why We Can't Have It All

The morning Maya Chen turned sixteen was still three weeks away, but she could already feel the weight of that magical number pressing against her imagination. Sixteen wasn't just a birthday—it was a threshold, a doorway into something bigger and brighter. With sixteen came freedom, or at least the promise of it. And Maya had plans. Oh, how she had plans.

She sat cross-legged on her bed, laptop balanced on her knees, scrolling through pages and pages of things she suddenly needed with an urgency that felt almost physical. The newest MacBook Pro—the one with the stunning display that seemed made for her graphics design projects. A Coach handbag, not just any Coach, but the vintage-look one with the distinctive C pattern that her favorite influencer had featured in seventeen separate posts. A trip to Paris for her best friend Elena's sixteenth birthday, staying at the actual hotel Elena's family owned near the Champs-Élysées. And, of course, a car. Not a beater, not a hand-me-down, but something reliable and maybe just a little bit cool.

Maya added up the numbers in her head. The laptop alone was $1,899. The handbag, $425. The Paris trip with flights and spending money, easily $2,500. And a decent used car, even a modest one, around $8,000. She was talking about nearly $13,000 worth of wanting. Thirteen thousand dollars. She let that number sit in her mind for a moment, feeling its weight.

Then she opened her banking app and checked her savings balance: $847.23.

It wasn't that Maya's family was poor. They weren't. Her parents both worked, her father as an electrical engineer and her mother as a hospital administrator. They lived in a comfortable house in a decent neighborhood. But comfortable didn't mean careless, and Maya had grown up hearing her parents talk about mortgages and retirement accounts and the cost of college tuition. She knew, even without anyone sitting her down for a formal conversation about money, that the gap between what she wanted and what she could have was roughly the size of the Grand Canyon.

She closed the laptop and stared at the ceiling of her bedroom, the late afternoon sun casting long shadows across her poster of Taylor Swift and her collection of polaroid photos pinned to a string above her desk. For a moment, she felt something she couldn't quite name—a strange, frustrated weight in her chest. It wasn't that she didn't understand why she couldn't have everything. She did. She wasn't stupid. But understanding something intellectually and feeling it emotionally were two very different experiences, and right now, at sixteen, with her birthday looming and her wish list stretching out before her like an impossible dream, she felt the gap between those two experiences very acutely.

This feeling—this sense that there is never enough, that resources are limited while desires are infinite—that feeling has a name. Economists call it scarcity, and it is perhaps the most fundamental concept in all of economics. In fact, it is so fundamental that most economists would tell you it is the very reason their discipline exists at all.

Let us begin, then, at the beginning: with the problem of scarcity.

Scarcity is not the same as shortage. A shortage occurs when the supply of something temporarily fails to meet demand—think of the toilet paper shortage during the early days of the COVID-19 pandemic, or the semiconductor shortage that affected car production worldwide. Shortages are situational, temporary, caused by specific disruptions in supply chains or unexpected surges in demand. They can be fixed. When the supply chain stabilizes or production catches up, shortages end.

Scarcity, on the other hand, is permanent. It is a condition that exists because of the fundamental nature of human existence itself. Scarcity occurs because our wants—our desires for goods, services, experiences, and security—are essentially unlimited, while the resources available to satisfy those wants are limited. There is never enough time, enough money, enough energy, or enough talent to do and have everything we could possibly imagine.

Consider time itself. Every human being on this planet receives exactly twenty-four hours in a day, seven days in a week, three hundred sixty-five days in a year. It doesn't matter if you are the richest person in the world or the poorest. It doesn't matter if you are a genius or struggle with learning. Time is the great equalizer, and it is always, always scarce. The billionaire cannot buy a twenty-five-hour day, and neither can the person sleeping under a bridge. Both face the same constraint: there is only so much time, and once it is spent, it is gone forever.

Or consider energy. Most of us wake up each day with a finite supply of physical and mental energy. We can rest and refuel, but even then, there are limits. A student can study for exams, but not indefinitely. A worker can put in overtime, but not forever. Even the most passionate artist eventually needs sleep.

The same principle applies to money, which is itself a representation of real resources. The money supply of any country, no matter how large, is finite. The global economy, despite its staggering size, produces only so many goods and services in any given year. There are only so many houses, so many cars, so many computers, so many haircuts, so many restaurant meals. We cannot conjure abundance from nothing.

And yet, human wants seem to multiply without bound. The ancient philosopher Aristotle wrote about human desires, but even he could not have imagined the sheer volume of wants that modern advertising and social media would create. Today, we are constantly surrounded by images and messages telling us that we need more, better, newer, shinier things. We need the latest phone, the trendiest clothes, the most exotic vacation, the most impressive home. Social media feeds our comparison with others, making us aware of desires we didn't even know we had. Every want satisfied seems to give rise to two more, a phenomenon psychologists sometimes call the "hedonic treadmill"—the tendency to constantly seek more, never quite reaching lasting satisfaction.

This creates the fundamental economic problem: unlimited wants colliding with limited resources. It is a problem that has confronted every human society throughout history, from hunter-gatherer tribes deciding whether to hunt deer or gather berries, to ancient civilizations deciding whether to build pyramids or fund armies, to modern nations deciding whether to spend on healthcare or education or infrastructure. The specific wants change, and the specific resources evolve, but the underlying tension remains constant. There is never enough to go around.

Maya lay on her bed, staring at the ceiling, feeling this tension in her bones. She could see, in her mind's eye, all the things she wanted, stacked up like a tower of treasures just out of reach. The laptop. The handbag. Paris. The car. But she could also see her bank account, that modest $847.23, and she understood with painful clarity that she would have to choose.

She couldn't have it all.

The thought felt almost rebellious, like denying something sacred. In a world of infinite scroll and endless options, where it seemed like anything was possible if you just wanted it badly enough, admitting that she couldn't have everything felt like a kind of surrender. But Maya was a thoughtful person, even at sixteen, and she knew in her heart that the universe didn't work on wishes. The universe worked on constraints.

Her mother came home an hour later, dropping her keys on the hall table and calling out a greeting. Maya went downstairs to help with dinner, and as they stood together in the kitchen—Maya chopping vegetables while her mother stirred a pot of soup—they fell into their usual easy rhythm of conversation.

"Mom," Maya said, after a few minutes of comfortable silence, "do you ever feel like you just can't have everything you want?"

Her m
