As we all know, Saudi Arabia has made a fortune by exporting crude oil every year. Saudi Arabia has proven crude oil reserves of 36.35 billion tons, accounting for 16% of the world's reserves, ranking second in the world. In 2020, Saudi Arabia exported 2.4 billion barrels of oil, with an average daily export of 6.6 million barrels, making it the largest oil exporter in the world. There are also natural gas reserves of 8.2 trillion cubic meters, ranking sixth in the world.

Saudi Arabia has good national welfare and free medical care. As long as you go to public hospitals and medical institutions, you don't have to spend money to see a doctor, treat a disease or stay in hospital. Moreover, seeing some serious diseases, such as those who need surgery, is very expensive, and they don't need to pay for it themselves, which is paid by the National Medical Foundation. Most of Saudi streets are luxury cars.

Most locals in Saudi Arabia only do some jobs such as government agencies, banks, state-owned enterprises, employees of large companies and managers of private enterprises, which are easy jobs with high wages. Most of those tired and dirty jobs are done by migrant workers, and the overall salary in Saudi Arabia is very high, so many people like India and the Philippines go to work in Saudi Arabia, and many people in China also go to work in Saudi Arabia.
