Studies and surveys have generally shown that while personal income in industrialized nations has increased over time (indicating a positive slope), happiness levels have not shown a significant increase and tend to remain relatively stable (indicating a more or less horizontal line). This reflects the concept that beyond a certain point, increases in income do not correspond with significant increases in perceived happiness.
