To what extent was Habsburg and early Bourbon rule successful in addressing the problems of Spanish America up to 1759?

Candidates will consider the merits or otherwise of the argument that Habsburg and early Bourbon rule was successful in addressing the problems of Spanish America up to 1759. They may, for example, choose to address each of the challenges individually and gauge the extent to which each was overcome, or they may choose to focus on the challenges that were overcome and those that were not in discrete groups. Challenges that might be addressed include, but are not limited to, the need to provide an efficient administrative system to rule a vast territory, the potential for religious orders to both assist their administration and challenge their authority, the impact of declining trade as well as opposition to Spanish trade monopolies and the threat of both foreign intervention and internal revolts.
