Why is Sweden one of the most equal societies in the world?

Sweden is one of the most equal societies in the world because of its commitment to social welfare and progressive taxation policies. Sweden has a long history of providing generous social benefits to its citizens, including free healthcare, free education, and generous parental leave policies. Additionally, Sweden has a progressive taxation system that taxes higher incomes at a higher rate than lower incomes, which helps to reduce income inequality. Finally, Sweden has a strong labor union movement that helps to ensure that workers are paid a fair wage and have access to good working conditions.
