Ah yes the TIbet region of China well known for being the entire reason any of China has wealth. Why it's so full of gold you just stumble over it walking down the street and as we know the only reason China has any money or power is the magical land of gold known as Tibet which allows them to ship gold all over the world and just print money!

Oh wait. That's not true at all. Tibet is actually one of the lesser developed regions owing to its distance from the sea, ports and industry located on the eastern coast for export, as well as its arid land being unsuitable for large scale agriculture and as a result the amount it contributes to China's overall economy is likely minuscule compared to a powerhouse like Guangdong. Of course we and the Chinese take into account the circumstances of Xizang which is why:

As of at least 2019, Tibet has the largest total per capita government expenditure of any region in China, including on health care, the highest per capita government expenditure on education, and the second highest per capita government expenditure on social security and employment.

Because China understands collective economic benefits and security.
