Not to stump for China prop, but from what I could see and the things I overheard in private, CCP-driven economic development may not be the core issue, or at least the Tibetan feeling appeared to be quite mixed - prior to CCP rule, the local religious leadership was not interested in development, so to some greater or lessor extent the development is not unwelcome and it has been an economic / technological / quality of life boon for no small number of Tibetans.

That said, what they didn't say but you could just walk outside and FEEL, was that this development has come along with a very apparent technocratic surveillance police state and a whole cart suspension of Tibetan political and cultural self-actualization...and this is at it's most benign.
