Tibetans in China definitely have a better and brighter future compared to the Tibetans in exile. The Chinese government has given them everything they need to help them grow, for example, educations, jobs, etc. They are given an equal opportunity, it is up to them if they want to go for it. The Tibetan culture and language are still preserved quite well in China.
The Tibetans in exile are neither here nor there. They are living in a land that doesn't belong to them. They don't have an identity, they are just refugees. Most of them are not living in a very good condition. The younger generation is losing touch with their own culture and language. Many of them can't really speak very good Tibetans.
I would say the Chinese government has done so much more for the Tibetans than the CTA. The welfare of the people is never the priority of the CTA. Even though they receive so much fund for the past 60 years, not much actually goes to the Tibetans or used to improve the quality of life of the Tibetans. That is also why fewer Tibetans are escaping China to come to India.
