Many western press, governments and ordinary people choose to believe in the stories spun by the exiled Tibetans than to view the improvements to the lives of Tibetans objectively.
The Dalai Lama and his exiled Tibetan supporters have become westernised and lost much of their Tibetan culture even though religious practices are retained from theocratic days. By the same argument, even the Dalai Lama could not prevent cultural genocide among his supporters. This is inspite of reports that the exiled government is autocratic, discriminatory against other Tibetan sects and practises nepotism.
In contrast, Tibetans living in China are free to learn their own language in elementary and high school level. However, practical reasons necessitate that they become fluent in Chinese Mandarin language which is the medium of instruction for tertiary education throughout China. Many non-Anglo Saxon ethnicities in the western world have to learn English as the official language for education and work. There is nothing so abhorent and fearsome about it.

Unfair and Disproportionate China bashing
Where was the world when the Indonesian government committed cultural genocide against ethnic Chinese citizens in the 1950s and 1960s? Discrimination was carried out to the extreme to undermine Chinese businesses and erase all traces of Chinese identity. It was unfortunate that it happened during the Cold War and the free world tacitly applauded these human rights violations. Similarly, the racially motivated riots in the 1990s despite in a less hostile international environment, also only received scant mention in the press, without much criticism or condemnation from western governments.
Reflecting on oneself, the atrocities committed against native Americans and Australian aboriginals that have yet to be fully vindicated compose another thesis for critics to ponder before jumping on random petty incidents that cloud the bigger picture.
Unlike these marginalised groups, affirmative action is shown towards ethnic minorities, more favourably towards Tibetans, in the form of scholarships with lower selection criteria and enjoy various forms of subsidies not available to majority of the Chinese population. Critics either do not know, or not bother to find out, or simply have the audacity to brush aside pertinent facts.
It is only logical that a caring government would create wealth to distribute wealth. Without doubt, every society has tensions between the very rich and bottom of the social ladder who have fallen between the cracks. Honestly, how many of us buy the arguments of looting during the London riots recently. Envy and getting back at unethcial capitalists are lame excuses to plunder and kill innocent people, many of whom are middle class people trying to make a honest living. Are the value of Chinese Han and Hui Muslim lives worth less than the victims of the London riots?
Like some of the "spontaneous" revolutions in other parts of the world, they would not have been ignited or spread without the instigation of exiles and their western clandestine sponsors. From hindsight, most Chinese and world citizens would appreciate the need for firm security when self interested rebels overstep their privileges, rights and responsibilites to harm the interests of the majority regardless of religion, social status and ethnicity.
