If the Tang Dynasty managed to maintain internal stability, avoiding major internal conflicts and rebellions, there might be less inclination for the government to scapegoat foreign religions. A prosperous economy could also reduce the likelihood of the government seeking external targets for blame. Economic stability might lead to a more tolerant attitude towards different belief system. On top of that if the Tang rulers implemented more inclusive policies towards various religions, fostering a climate of religious tolerance, it could discourage persecution. This might involve recognizing the positive contributions of Buddhism and other religions to Chinese culture and society.
While it is true that the Huichang Persecutions released resources by targeting various religious institutions, the assumption of a more rapid collapse of the Tang dynasty in the absence of such crackdowns is icorrect. The persecutions, while providing short-term economic relief, also had detrimental long-term effects on stability and social harmony.
The Tang Dynasty did face economic challenges, including the so-called "Fubing System," where military service was tied to landownership. Economic issues were not solely caused by religious institutions, but rather by a combination of factors such as mismanagement, corruption, and military expenditure.
Firstly, the crackdowns on Buddhism, and other religions created social unrest and discontent among the populace. While it's true that some Buddhist monasteries were tax-exempt, they also played significant roles in economic development. Many monasteries were involved in agricultural activities, education, and even medical services. They served as centers for technological and agricultural innovation, contributing positively to the economy. The crackdowns caused social unrest and the potential for internal strife and rebellion may have outweighed the immediate economic benefits.
The crackdowns on Buddhism were not solely motivated by economic considerations. Political and ideological factors were equally significant drivers of these measures. The state's attempt to exert control over religious institutions was intertwined with efforts to consolidate political power and shape ideological narratives. Suppressing Buddhism did not automatically lead to a more stable or prosperous state. Instead, it disrupted a complex network of economic, cultural, and social contributions that Buddhism, among other religions, made to the fabric of Tang Dynasty society.
