What are the benefits of Sweden, Finland and those countries? Specific point

Sweden is one of the countries with the highest welfare in the world and one of the few countries that did not participate in the Second World War. After the war, Sweden concentrated on economic development, implemented a wide range of social welfare policies and established a relatively complete social welfare system. Social welfare projects, from paid long-term maternity leave for parents to sick leave allowance for medical insurance, from unemployment insurance and pension to compulsory education, are called "protection from cradle to grave".

Sweden is a fund for welfare protection through high personal income tax rate and high taxes. There are many taxes in Sweden. For individuals, in addition to personal income tax, there are interest tax and inheritance tax. And the income from other business activities such as stock trading funds and buying and selling houses. When you buy goods, you must pay VAT. Companies must pay employer tax. Every year from April to June, Swedes should take the initiative to declare all their annual income to the tax bureau.

Some scholars believe that this Scandinavian welfare model is a model between socialism and capitalism and a mixed economy. Due to the economic recession in Europe, Sweden's welfare system is also facing difficulties. The population is aging and young people lack enthusiasm for employment. These are common problems in high welfare countries. Sweden is carrying out a series of reforms to enhance economic vitality and improve the system.
