Some people have to accept nearly $10,000 bills with trembling hands as soon as they connect their dislocated wrists in the hospital. High medical expenses are inseparable from high medical expenses. The medical expenditure in the United States is the highest in the world, with 3.6 trillion yuan, accounting for about 18% of the total GDP. The medical cost mainly comes from two aspects. First, the money spent on doctors. In the United States, the entry threshold for doctors is very high, the learning cost is high and time-consuming, and the supply is less than the demand, so the cost of hiring doctors is very high. Not only that, American litigation culture is deeply rooted in people's hearts. When there is a problem between doctors and patients, some patients directly file a lawsuit regardless of who is right or wrong. The litigation cost of patients is very low, but hospitals have to pay huge compensation fees every year, and doctors themselves will also pay a lot of litigation fees or buy direct medical liability insurance. Hospitals and doctors also want to make profits, so in the end, the money is shared in medical expenses.
