The $7 Coffee Fallacy

For years, personal finance advice has centred on a simple idea: cut small, everyday expenses and you will eventually build wealth. The $7 coffee has become its most recognisable symbol, yet the math behind it, roughly $2,500 a year, collapses quickly when placed against how modern luxury actually works.

Consider an Hermès Birkin. While entry prices start at around $13,500, according to Sotheby’s, the real barrier is not price, but access. Customers are often required to build purchase histories running into the hundreds of thousands before even being offered the opportunity to buy one, and even then, what is offered is not a matter of preference, rather ‘whatever the brand deigns to provide them with’.

Does this purchase deliver the status it promises? Not quite.

Because the target has already moved. Rarer variants exceeding $200,000 sit above it, making the entry-level Birkin less a marker of exclusivity, and, more a point of entry. What is accessible to a millionaire, in other words, is often structurally uninteresting to a billionaire.

This is not incidental. It is how luxury is designed to function.

The economist Thorstein Veblen described this through the idea of Veblen goods, where value is derived from exclusivity rather than utility, but what has changed is the speed at which these signals now decay, as access expands and imitation accelerates.

Take, for example, a smoothie at Erewhon, priced at roughly $20, compared to mainstream equivalents priced between $6-$10, creating a 2x–3x premium for broadly similar nutritional value. The difference is not driven by health outcomes, but by what the purchase communicates: identity, and sadly, the desire to display proximity to a certain lifestyle.

The question, then, is not what the Erewhon smoothie provides, but what it signals.

And signals, by design, do not compound.

What does compound, in fact, are functional improvements, investments into our life, that reduce friction, save time, and improve daily life. These investments, like the $7 coffee, are rarely visible, but, provide us with the experience that possibly uplifts our everyday.

So, while that $7 coffee will not make you wealthy, cutting it out will not bridge that gap, a gap that is structurally designed to keep moving toward an undefinable target.

So, in a system where signals are constantly re-priced and repositioned, the more meaningful distinction is not between spending and saving, but between optimising for ‘status’ and optimising for ‘life’.
