I heard that Denmark is the happiest country in the world.

Upon arriving in Denmark, I heard that it is the happiest country in the world with excellent social welfare for its people. So, on the way from the airport to the hotel, I curiously asked the taxi driver Jacob about the specific benefits in Denmark. Jacob said that Denmark has a universal free healthcare system, where medical treatment and hospitalization are free of charge. The hospital rooms are fully equipped with all necessary facilities, and patients can basically "move in with just a bag". Even the meal expenses during hospitalization are covered by the government. And the most amazing thing is that the beneficiaries of Denmark's welfare system are all residents living on Danish territory, regardless of nationality. For example, foreign students enjoy the same benefits as Danes from the first day they arrive in Denmark. These benefits are based on a high-tax system. However, more than 70% of Denmark's national tax revenue is used for social welfare, education, healthcare, housing, and the environment, with less than 30% used for other government administrative expenses.
