Even if we put aside the entire forced-sinicization-through-cattleprods-or-worse aspect of CCP's programs of premeditated cultural genocide in the homelands of Uighurs and Tibetans, the Han Chinese state's policies at all levels of education are designed to rewire the "minorities" for the role CCP has designed for them. Do the "minorities" have any say in their own curriculum? Well no, and those who protest find themselves serving a long and generally unpleasant sentence in a "knitting camp" or some other euphemism.
These so-called minorities have the priviledge of using their own language for the first few years of education at best, much of which is spent on adopting the Party's own sino-centric views and of course the one true language of the Han. Only in token handful of cases is higher education available in their native language, but even then Party propaganda and Pekingese remain key subjects. The CCP wants to be absolutely certain that any hopeful "minority" elites are loyal to the Chinese regime.
Roads and railways are great for moving Han settlers and military around the "autonomous regions" and for shipping out the various natural resources where the CCP wants them. What proportion of the reported GDP growth can be accounted to the "minorities'" own economic activity versus the Chinese state, Chinese industries and the Han settlers?
If the actual Tibetans and Uighurs are so damn happy with the progress the Chinese Communist Party is handing down, why the fsck aren't journalists or even UN human rights observers allowed to visit their homelands? Why all the all-encompassing mass surveillance and intimidation?
If this was happening in my country and to my people, people would be horrified even by any single program imposed, let alone the entire totalitarian sinicization package.
