The Indian government has been very kind indeed. It is indeed impossible for them to sponsor all moansteries, but they do have financial assistance scheme, such as Scheme for Financial Assistance for the Preservation and Development of Buddhist/Tibetan Culture and Art, whereby financial assistance is given up to a maximum of Rs.30 lakhs per year for any single organisation. Especially in case of the organisations running a school for imparting monastic education, the financial assistance may be given beyond the ceiling, on the recommendation of the Expert Advisory Committee and approved by the Minister (Culture) in consultation with the FA, Ministry of Culture.
India is not rich. Based on GDP, it is considered a lower-middle income economy. The unemployment rate for 2010-11, according to the state Labour Bureau, was 9.8% nationwide. As of 2011, India's public debt stood at 68.05% of GDP and inflation remains high with 7.23% in April 2012. So, the Tibetans should feel grateful that the Indian government actually helps the Tibetans whom they have already generously promised to host for 99 years.
Like what dsiluvu said, Tibetans should really stop making troubles for their kind host. I have heard that the Tibetans in South India have been creating problems, such as asking the Indian government to deport Tibetans who arrived to join Dorje Shugden monasteries like Shar Gaden and Serpom. Can you imagine how frustrated the Indian officials must have been? Even “minor” issue like a religious ban cannot be handled by the Tibetan communities and they have to trouble their Indian host. Tibetans should really look at why they are still in diaspora and start thinking of what will happen to their next generation as the 99 years is soon to be over.
