It is one of the most satisfying stories we tell: the child who grew up with little, who went without, and who outstripped the pampered rich kids to build a life of substance. There is a real truth buried in it, but the story is also dangerous, because taken literally it romanticizes deprivation in a way the evidence flatly contradicts. Growing up with less money is not, on average, an advantage. It is a serious disadvantage. So the claim needs unpacking with some care, because the grain of truth in it depends entirely on what you mean by less, and getting that wrong turns a useful insight into a harmful myth.
First, the myth: poverty is not a gift
Start by clearing away the false version, because it does damage. The research on childhood poverty is about as one-directional as social science gets. Studies tracking people across decades find that low childhood socioeconomic status predicts worse adult outcomes across nearly every dimension, from physical and mental health to education and earnings, and the disadvantage often becomes biologically embedded, showing up in adult health even after later income is accounted for.
A child raised in genuine material hardship is, statistically, more likely to face worse health, less schooling, and lower income as an adult, not more. The successful person who rose from poverty is real, but they succeeded despite their start, not because of it, and for every such story there are many more where the disadvantage simply compounded. Any honest version of children raised with less become adults with more has to begin by refusing to romanticize actual poverty, which harms far more children than it forges.
What the claim gets right: less is not about money
So where does the intuition come from, given that it feels true to so many people? The answer is that the useful sense of less is not less money at all. It is less over-provision. The comparison that actually holds up is not poor children against rich children, but children who had to develop competence against children who had everything done for them.
There is a growing body of work on the hidden costs of affluence, showing that children who are heavily indulged, shielded from every difficulty and handed whatever they want can struggle later with motivation, resilience and a sense of purpose. The problem there is not the money itself but what easy abundance can do: it removes the friction against which capability is built. A child who never has to wait, work or want for anything is denied the very experiences that grow persistence and self-reliance. That is the real engine behind the story, and it has nothing to do with poverty and everything to do with over-provision.
The evidence for responsibility
One of the clearest illustrations concerns responsibility, the ordinary business of being expected to contribute. Children raised with less, in the sense of fewer luxuries and more expectation that they pitch in, tend to acquire practical competence early. And that early contribution has a measurable long tail. Research by Marty Rossmann at the University of Minnesota found that participating in household chores from a young age, around three or four, was one of the better predictors of success in the mid-twenties, while starting only in the teenage years did not carry the same benefit.
This should be read carefully, since it is correlational and the popular versions of it, often dressed up as a single dramatic Harvard finding, overstate the case. Doing chores does not magically manufacture a successful adult. But the underlying pattern is consistent with a great deal of developmental research: children given real responsibility, who are needed rather than merely served, build a sense of capability and accountability that tends to serve them well. A household with less to go around often supplies that responsibility as a matter of necessity.
The things less can carry, and their cost
There are other qualities that a lean upbringing can foster, and they are worth naming without overselling. Not taking comfort for granted can build genuine gratitude and drive. Wanting things you cannot immediately have can teach patience and fuel ambition. Having to make do can breed resourcefulness. These are real, and they are part of why the story resonates.
But two honest caveats matter. First, these are tendencies, not guarantees, and the same scarcity that builds grit in one child crushes another under stress, anxiety and narrowed horizons. Second, these traits usually come at a price that the triumphant narrative conveniently omits: the adult who learned relentless drive from early hardship often also carries its scars, from money anxiety to difficulty ever feeling secure. Whatever less gives, it rarely gives it for free.
The honest synthesis
Put it together and the sweet spot is neither deprivation nor indulgence. It is something more like enough plus expectation: material security sufficient for health and opportunity, combined with the deliberate absence of over-provision, and set inside warmth and high expectations. Children thrive when they are safe and supported but still needed, still stretched, still allowed to struggle with things and to want for some of them. That combination can occur at any income level, which is precisely the point. A wealthy family can raise capable, grounded children by refusing to smooth every path, and a modest one can do the same through necessity.
Where it leaves us
So the claim survives only in translation. Children raised with less money do not, as a rule, become adults with more; the evidence on poverty is clear and sobering, and pretending otherwise hurts the children it claims to celebrate. But children raised with less indulgence, less cushioning, less done for them, and more expected of them, often do develop the competence, resilience and drive that serve an adult well. The valuable thing was never scarcity. It was responsibility, effort and the dignity of being needed, none of which requires a hard childhood, and all of which any family, at any income, can choose to provide.
