There’s a phrase my family uses all the time: “the boots theory.”

Honestly, I don’t even know where I first heard it. At some point, it just entered family vocabulary. I mention it enough that my husband and son both immediately know what I mean when I say something is “a boots theory problem.”

Usually, I’m talking about something frustratingly disposable. Shoes that fall apart too quickly. Appliances that mysteriously die right after the warranty expires. A cheap item that seemed like a bargain until replacing it three times cost more than buying the better version would have in the first place.

It wasn’t until recently that I learned this idea actually came from Men at Arms by Terry Pratchett and has an official name: the Vimes Boots Theory of Economic Injustice.

Which sounds far more dramatic than talking about shoes should sound.

But honestly? The reason the idea sticks around is because people recognize the truth in it immediately.

The theory is simple. A wealthy person can afford a high-quality pair of boots that lasts for years. A poor person can only afford a cheap pair that wears out quickly. Over time, the poor person ends up spending far more money replacing bad boots than the wealthy person spent buying one good pair in the first place.

The wealthy person saves money by having money.

The poor person pays more because they don’t.

And once you notice this pattern, you start seeing it everywhere.

Cheap kitchen appliances that break after a year or two. Fast fashion that stretches, pills, or tears almost immediately. Furniture made from particle board instead of solid wood. Cars that become endless repair projects because buying a reliable vehicle upfront wasn’t financially possible. Even groceries sometimes work this way. Buying in bulk is cheaper long term, but only if you can afford the larger purchase at the beginning.

Cell phones are probably one of the clearest modern examples. For years, many people joked about phones mysteriously slowing down right around the end of a two-year contract. At the time, it sounded paranoid. Then we later learned there actually were cases of manufacturers intentionally throttling older phones under the explanation of battery management.

Suddenly people’s suspicions didn’t seem quite so ridiculous.

Now, to be fair, not every product problem is some evil mastermind twirling a mustache in a boardroom. Sometimes products are cheaper because consumers demand lower prices. Sometimes manufacturing priorities shifted toward speed and mass production. Sometimes companies genuinely are balancing durability against affordability.

But there is also something called planned obsolescence, where products are intentionally designed with limited useful lifespans because companies benefit when consumers need to replace things more often.

And honestly, I think most people feel this intuitively.

That’s why so many older adults say things like, “They don’t make things like they used to.”

In many cases…they genuinely don’t.

Repair culture has largely been replaced by replacement culture. Products are sealed shut instead of repairable. Parts are difficult to replace. Software updates eventually stop supporting older devices. Entire industries now depend on recurring upgrades rather than long-term durability.

But the deeper reason the boots theory matters isn’t really about consumer frustration. It’s about understanding how poverty compounds itself.

People often talk about financial struggles as though everyone is making choices from the same starting point. But the boots theory reminds us that having money upfront changes what options are available to you in the first place.

If your refrigerator dies and you only have enough money for the cheapest option, you buy the cheapest option. If your work shoes fall apart and payday is still a week away, you buy what you can afford right now—not the pair that would last five years.

Poverty forces short-term survival decisions.

And those short-term decisions can become incredibly expensive over time.

It’s not just products, either. It’s overdraft fees. Payday loans. High-interest financing. Medical issues delayed because someone can’t afford preventative care. Late fees caused by living paycheck to paycheck. The less financial cushion someone has, the more expensive everyday life often becomes.

That’s what makes the boots theory feel so relevant right now.

Most people I know are trying to stretch everything further than they used to. Groceries are expensive. Housing is expensive. Insurance is expensive. Repairs are expensive. People are exhausted from trying to optimize every dollar while also being surrounded by products and systems that often feel intentionally temporary.

And I think that’s why this idea continues to resonate decades after Terry Pratchett wrote it in a fantasy novel.

Because it was never really about the boots.

It was about the reality that systems often reward people for already having resources while making life harder and more expensive for those who don’t.

Once you see it, you can’t really unsee it.

And apparently, in my family at least, it becomes something you casually reference at the dinner table for years before realizing it came from a fantasy book.

If this post resonated with you, I’d love to hear your own “boots theory” examples in the comments. What’s something you’ve noticed costs more in the long run simply because the better option wasn’t affordable upfront?
