Why might the italian city-states have resisted the exploration around the world?

One of the reason of the Italians have resisted the exploration around the world is an interesting matter to explain. One reason  to mention is  the case of atlantic for example.

Some authors have explained that the Atlantics voyages mainly were for business reasons. The Portugueses and Spanish wanted to find an alternative  route to India where valuable spices were produced.

They wanted an alternative because the italians had a monopoly on the most direct route. For this reason the italians did not need look for a different route as they already had one.  

assuming that by westerners you mean americans. that they were mean and controlling and abusive to its peasants.

explanation:

the high price of student services and administration are two reasons for the rapid increase in cost.
