There were two schools of philosophy that aimed to stop the immensely destructive civil wars that had ravaged China for centuries. Legalism produced a military machine that steamrollered all the other states into submission to Qin. However, once it was imposed on a wider scale, it proved to be hugely unpopular - imagine Communism at its most inhumane. In contrast, Confucianist government was both practical and involved far less social adjustment than Legalism. It's a truism that benevolent dictatorship is the best form of government. Confucianism aims to produce benevolent dictators.
I think you're confusing the symptoms of failed Confucianism with the idea of Confucianism itself. The philosophy doesn't seek those abuses you speak of. Instead, it has the ideal of a benign ruler who dispenses justice, and who sends his officials to dispense justice and good government on his behalf. Hence top-down government. There are stories of Chinese officials who go to their province, find injustice, and correct it. That's Confucianism as it ideally functions. What you're probably more used to is the Germanic idea of government, where there are councils where the thegns may speak their mind to their chief. The clash between this and the Norman ideal of absolute regal rule produced the English ideas of liberty and the rule of law, which you're probaby more familiar with, rather than the Confucian ideal of rulers dispensing the concept of justice. I know which I prefer, but it's best to try to understand the other idea before judging it.
