How is the hegemony of the US is reflected in structural power?

The role played by the US in providing global public goods.

Hegemony in this second sense that is structural power is reflected in the role played by the US in providing global public goods. By public goods, we mean those goods that can be consumed by one person without reducing the amount of the good available for someone else. Fresh air and roads are examples of public goods. In the context of the world economy, the best examples of a global public good are sealanes of communication (SLOCs), the sea routes commonly used by merchant ships. Free trade in an open world economy would not be possible without open SLOCs.
