Sibling relationships can be a blessing, but they can also be rivalrous—especially when one sibling earns more than another. A study from the University of Copenhagen found that second children earned, on average, about 2 per cent less than their firstborn siblings by the age of 30. These disparities can be subtle or extreme, and many readers wonder whether they should feel guilty or pressure themselves to help out family members who earn less.

They also raise questions about how birth order, education, and career choices influence earnings trajectories.

By opening this conversation, the FT hopes to shed light on how families navigate the complex emotional and financial terrain that arises when income isn’t evenly distributed.
