why would they change anything? if it's not broke, don't fix it. Sure they may make some changes. But again, why would they want to risk civil unrest?? Why would they want large scale immigration, an increase in crime rates, which would ultimately lead to less foreign investment. The agreement for fifty years gives the government the opportunity to change the one country two systems, but again, I don't see why they would want to ruin what is a very good money maker for them (China). The agreement doesn't say that after fifty years the SAR will cease to exist. No one ever thinks of it this way, in fact, it seems like more of the same scare mongering that was present before the handover, and the "doom and gloom" prophecies that never happened. I predict little or no changes post 2047.
