What is the 75000 theory?

The "$75,000 theory," proposed by Kahneman and Deaton in 2010, suggested that emotional well-being (daily happiness) increases with income but plateaus around $75,000 annually, meaning more money doesn't significantly boost day-to-day mood beyond that point, though life satisfaction (evaluating your life) still rises. While the initial theory was widely accepted, later research, notably by Matthew Killingsworth, challenged the plateau, finding that happiness generally continues to rise with income, though a joint study by Kahneman and Killingsworth later nuanced this, suggesting that for some, the plateau in daily happiness remains, while general life satisfaction keeps improving with wealth.

Many couples almost divorced but waited it out, finding crises passed.
