What is the difference between communism and Nordic "welfare" countries?

These are world-famous high-welfare countries where children are provided with care, education is provided, diseases are treated, the elderly are provided for, and the lives of workers and all vulnerable groups are guaranteed. Its prosperity comes from high welfare under high taxes and the equalization of income and consumption levels among various classes in society through redistribution. Relevant data show that in these Nordic countries, the difference between the highest income class and the lowest income class is 17 times before tax, and the difference after tax is only a little more than 3 times. There is no huge gap between the rich and the poor. In Sweden, the annual income of 3.5% of the poor population is around 100,000 yuan, which is higher than the well-off level in China. The per capita annual income of the labor force is equivalent to about 250,000 yuan, making it a typical wealthy country. Moreover, the society is harmonious and stable, and the crime rate is low. The national cultural level is high and the environment is beautiful. Politically clear and innovative.
