In Sweden, known as the "model" for high-benefit countries, non-workers receive almost the same benefits as wages and income, and do not pay taxes. Generous sick leave pay means that workers can get 90% of their wages if they are sick. Although the Swedes are the healthiest citizens in Europe, employees spend an average of no less than 50 days a year on sick leave, accounting for almost one-fifth of a year's work. Which of the following statements does not make sense? ['Welfare systems in some countries represented by Sweden need reform.', 'The welfare system is not a system conducive to social progress.', 'The welfare system has become a heavy burden on some European governments.', 'The pursuit of fairness will affect social development to some extent.']
