Why does Gen Z overconsume?

The premise of this question needs unpicking before it can be answered.

Gen Z don’t overconsume in any absolute sense. They can’t – they don’t have the money. This is a generation squeezed by housing costs, weighed down by student debt, entering a job market that’s tightening just as AI starts automating entry-level roles. The idea that they’re on a spending spree misreads the situation entirely.

Yet the “overconsumption” label persists. Scroll through commentary on Gen Z spending and you’ll find endless hand-wringing about hauls, fast fashion, impulse buying and financial recklessness.

What’s actually going on is more complicated – and more interesting – than the headline suggests.

What overconsumption actually means here

If overconsumption means spending beyond your means, then yes, there’s something to examine. Gen Z have a higher tolerance for debt than older generations. There’s nothing new here. Younger people have always been more comfortable stretching finances in the short term, less anchored by the long-term commitments – mortgages, children – that make older adults more cautious.

And context matters. This tolerance exists partly because traditional milestones feel out of reach anyway. When you can’t realistically save for a house deposit, the calculation changes. The psychological weight of debt is different when the alternative isn’t security – it’s just a slower grind toward the same uncertainty.

So Gen Z aren’t overconsumers in the way a previous generation might have been – splurging from abundance. They’re stretching limited resources in an environment where the old rules don’t apply.

Social and cultural drivers

Gen Z are the guinea pigs for smartphones. They’ve grown up shaping – and being shaped by – technology in ways that are both conscious and unconscious. Social media doesn’t just influence what they buy; it influences how they think about buying.

Visibility plays a significant role. Haul videos, unboxings, “what I bought this week” content – spending is performed and documented in ways previous generations never experienced. This creates pressure to participate, to keep up, to curate a lifestyle. It also makes Gen Z consumption highly visible to older observers, which distorts perception. We notice what we can see.

But there’s more than visibility at work. Gen Z have come of age during a period of genuine chaos – pandemic, cost-of-living crisis, wars, climate emergency, the arrival of AI. These forces have shaped them profoundly, often without their conscious awareness. They’re light readers of news; their social feeds aren’t representative of the wider world. This can leave them without frameworks for understanding why things feel hard – and more likely to attribute systemic problems to personal failings.

The mental health implications are significant. When you can’t see the forces acting on you, difficulty feels like your fault. No wonder anxiety and depression are prevalent in this cohort.

Economic insecurity and confidence

Konfidant’s data shows consumer confidence among Gen Z is under pressure. Traditional paths to security – graduate job, career progression, home ownership – are closing down. Student debt that felt normalised at 18 starts to weigh heavily at 25. Future earning potential feels capped in ways previous generations didn’t experience at the same age.

The response isn’t fatalism exactly, but it’s not careful long-term planning either. Focus is on getting through today, this week, this month. When the traditional path clearly isn’t working, Gen Z look for transformational unlocks – skipping university, moving back with parents, starting a side hustle.

These decisions tend to be heart-first, not spreadsheet-driven. The logic is often “others are doing it” or “I saw it on social media” rather than careful research. That’s not a criticism – sometimes decisions of this magnitude have to come from the gut. Too much information and you’d talk yourself out of it.

Treating as coping mechanism

Treat culture exists across all generations – small indulgences as compensation, reward or relief. But for Gen Z, treating has a different texture.

It’s less about little moments – a walk in nature, time with friends – and more about things or bought experiences. There’s more money attached to each treat. And because there’s pressure to be saving (even when saving feels pointless), there’s more guilt attached too.

Crucially, Gen Z treating is disproportionately more often a coping mechanism than a celebration. It’s used when life isn’t adding up rather than as a reward for a job well done. The function is zoning out, numbing, escaping – not savouring.

This matters for understanding “overconsumption.” Some of what looks like reckless spending is actually self-medication in a generation with limited other outlets and high levels of anxiety.
The more valuable insights lie in what’s changing.

The say/do gap

One pattern that emerges clearly in the data: Gen Z’s stated values and actual behaviour don’t always align.

The “say” can be quite ethical – sustainability matters, fast fashion is problematic, conscious consumption is important. The “do” reflects the commercial realities of tight budgets – buying what’s affordable, choosing convenience, prioritising price.

This isn’t hypocrisy. It’s constraint. But it does mean that surveys capturing attitudes alone will miss what’s actually happening. Self-reported values tell you what people believe they should do. Behavioural data tells you what they’re actually doing and why.

Signs of backlash are emerging – de-influencing content, underconsumption trends, conscious rejection of the buying cycle. But how deep this goes versus how much is another performance remains to be seen.

Why surveys under-capture Gen Z behaviour

Traditional surveys struggle with this cohort for several reasons.

There’s the say/do gap – stated attitudes diverging from actual behaviour. There’s social desirability bias – Gen Z are particularly attuned to what they’re “supposed” to think. And there’s a lack of self-awareness about the forces shaping them. If you’ve never consciously processed how the pandemic or cost-of-living crisis affected your spending psychology, you can’t report it accurately in a survey.

Konfidant’s approach addresses this by blending quantitative scale (2,000 weekly interviews) with qualitative depth from a longitudinal community – capturing behaviour over time, not just attitudes in a moment. We deliberately over-sample Gen Z because understanding the next wave of consumers requires more than surface-level data. The texture matters.

Rethinking the overconsumption narrative

So why does Gen Z overconsume? The honest answer: they largely don’t – at least not in the way the question implies.

What they do is:

• Spend visibly, in ways that attract disproportionate attention
• Stretch limited resources, with a higher tolerance for short-term debt
• Use purchasing as a coping mechanism more than a reward
• Make heart-first decisions when traditional paths feel closed
• Say one thing about values, do another when budgets bite

Whether that constitutes “overconsumption” depends on your frame of reference. Compared to their means, there’s genuine financial stretch. Compared to older generations at the same life stage, the picture is more complex – different pressures, different channels, different visibility.

The more useful question isn’t whether Gen Z overconsume. It’s why their relationship with money and spending looks the way it does – and what brands should understand about the anxiety, adaptation and aspiration sitting beneath the surface.
