It really only takes a single spark and semi-charismatic leadership to start a revolution if there is widespread hostility to the ruling party. The Taiping nearly overthrew the Qing dynasty, and they were led by a deranged religious fanatic who had a breakdown after failing repeatedly to get into civil service and claimed to be the second coming of Jesus. This came at a time when the expansion and prosperity of the Qianlong emperor was well in the rear-view, and population pressures, corruption, monetary shifts (the massive influx of Spanish silver in exchange for tea, silk, china, etc, was replaced by opium, which threw off the rates of exchange between gold, silver and cash) and other factors were resulting in a real decline in standard of living. Today, any rebellion would probably need to involve a dissatisfied faction of the PLA, because China is so disarmed - the Communists arose at a time when the supply of firearms within China was probably at it its all-time high, between the decades of warlord control, the war with Japan, and military aid arriving from all sides in WW2. And quite frankly, the KMT armies were not particularly professional or formidable adversaries, compared even with the rank-and-file of the PLA today.
