This is allowed because it does no real harm to the ruling party. Remember even though many western country visitors can enter HK without any visa [1], interestingly the Chinese people need a special pass to visit HK [2]. I won't be surprised that the 0.2% of the population that visit HK are mostly elites who have little interest in changing the system that favors their interest.
