The comparison trap
Leon Festinger’s Social Comparison Theory (1954)
proposed that humans have a drive to evaluate their opinions and abilities,
often by comparing to others—and that the pull to compare
falls as the other person gets less similar.
His example: a beginner at chess doesn’t measure himself against
the masters. Apply that to money, and
we don’t compare ourselves to billionaires or to strangers. We
compare to our friends, our colleagues, our peers. The people
sitting across from us at dinner.
Why dinner amplifies comparison: Restaurant
spending happens in front of everyone.
Unlike rent, savings, or investments—which are private—what
you order is public. Everyone at the table sees whether you
chose the $16 pasta or the $48 ribeye.
Wilkinson and Pickett, the authors of The Spirit Level,
compare whole societies. Their finding: lack of trust and other social
problems are more common where incomes are more unequal. They argue
the link runs through status competition, which turns others into
rivals and weakens social relations.
Their data covers societies, not friend groups, so this is an analogy:
a friend group with a wide income spread is, in miniature,
an unequal society. It’s easy to see the same withdrawal
happen. The lower earner starts declining invitations. The
higher earner stops suggesting expensive restaurants. The group
slowly contracts around the discomfort nobody names.
67%of Americans aged 25 to 64 say they’ve declined social events
in the past two years primarily because of cost, according to a
2026 CFP Board survey.
