Undoubtedly Tibet has benefited from moving from a feudal society and the Dalai Lama was aware of the need for this many years ago, while he still lived in Tibet. Indeed he saw, at that time, that Communism had much to offer. However not everyone has benefited equally:
Shakya said Beijing must be stunned by the Lhasa riots because Tibet,
under Zhang's firm hand, was thought to be pacified. In 2006, China
opened the world's highest railroad, which cost $4.1 billion and
traverses the Tibetan plateau to connect isolated Lhasa with the rest
of the country. Beijing described the railroad as a vital tool in
developing the Tibetan economy, the poorest in China.
But many Tibetans regard the railroad as a threat. China has poured
money into Tibet in hopes that economic development would dilute
Tibet's religious fervor and win over a younger generation. For many
Tibetan families, life has improved; trade and tourism are also rising.
But Beijing has also encouraged huge numbers of Chinese migrants and
traders whose presence has diluted the Tibetan majority.
