The Spain of lead actor secondary power of world history

Behind the Spanish golden century, the really interesting question is: Why LESPAGNE increased dune situation where it dominated the Western world (1550 completed viceroyalties creation of the new world, domination of the kingdoms of Naples and Sicily, the Netherlands and the Duchy of Milan) to a secondary power in just 150 years (dEspagne succession war in 1701)?

For Bennassar, this is a set of phenomena:
- Using lor and money for the new world of non-productive investments (palaces, art) and military spending (the resumption of the war of the Netherlands in 1621 will cost 3M ducats a year for 7 years, against a contribution India to the royal treasury "only" 2M ducats, approximately 20% of the revenue of the State, which itself touches that about a quarter of total flows) LESPAGNE has missed the birth of the capitalist bourgeoisie with the expulsion of the Jews in 1492, and persecution against conversos, and didnt created proto-industrial fabric to transform raw materials
- Slow gold and money flows of the new world (peaking in 1620)
- Decrease in population due to limited food production (famines, plagues in 1597 and 1647) and Quà loss in men due to both lémigration to the new world and wars "exported" (Nether- Spanish Netherlands, Italy)

In addition to the answer to this question, the organization thematic (rather than chronological) to discover some interesting anecdotes, such as the organization of the king matrix boards (geography x function), and the low importance of the sixteenth and seventeenth Catalonia Century (700k inhabitants in Catalonia and Laragon gathered against 7M for Castile, with a population density nearly two times less, in 1620, French immigrants accounted for nearly 25% of the population in Catalonia and Aragon)
