Tibet is a better place to live now. It is very modern and convenient, the tourism industry is very developed and people have better career opportunities in Tibet. Not only that, many old Buddhist monasteries and holy sites in Tibet are also under restoration projects undertaken by the Chinese government.
The Chinese government gives equal right to everyone. They can choose the belief they want to follow as long as the belief does not create disharmony in the society. For example, there is no ban or discrimination of Dorje Shugden practice in China, the Chinese government gives people the freedom to practice it because Dorje Shugden followers are spiritual practitioners, they are not involved in politics.
If we look at the Tibetan community in India, the living condition is bad. Tibetans are still refugees, nobody knows what is laying ahead of them. Many of them are living in poverty as the CTA does not have any plan to help them to become more competitive. There is no religious freedom, just look at how the CTA discriminate against and segregate Dorje Shugden followers. Hence, it is better to go back to China!
