The government of the PRC also rejects claims that the lives of Tibetans have deteriorated, pointing to rights enjoyed by the Tibetan language in education and in courts and says that the lives of Tibetans have been improved immensely compared to the Dalai Lama's rule before 1950. Benefits that are commonly quoted include: the GDP of Tibet Autonomous Region (TAR) today is 30 times that before 1950; it has 22,500 km of highways, all built since 1950; all secular education in the region was created after integration into the PRC; there are 25 scientific research institutes, all built by the PRC; infant mortality has dropped from 43% in 1950 to 0.661% in 2000; life expectancy has risen from 35.5 years in 1950 to 67 in 2000; the collection and publishing of the traditional "Epic of King Gesar", which is the longest epic poem in the world and had only been handed down orally before; allocation of 300 million Renminbi since the 1980s to the maintenance and protection of Tibetan monasteries. The Cultural Revolution and the cultural damage it wrought upon the entire PRC is generally condemned as a nationwide catastrophe, whose main instigators (in the PRC's view, the Gang of Four) have been brought to justice and whose recurrence is unthinkable in an increasingly modernized China. The China Western Development plan is viewed by the PRC as a massive, benevolent, and patriotic undertaking by the eastern coast to help the western parts of China, including Tibet, catch up in prosperity and living standards.
