The article explores how people's age influences their support for changes in social security benefits. Younger people tend to prefer smaller benefits, while older individuals favor larger benefits. By analyzing the financial self-interest of voters at different ages and sexes, the researchers found that a majority would oppose reducing benefits. Even with various factors like taxation and mortality rates considered, a decrease in benefits would likely be rejected by selfish voters. The study also looked at potential outcomes of votes on changing the retirement age.
