Final answer:
England's cultural lag was manifested in the formation of an exclusionary identity, while also acting as a cultural borrower through trade and imports.
Step-by-step explanation:
The cultural lag in England can be identified in the formation of an Anglo-Saxon identity in the early 19th century, which denied agency to other cultural groups within the British Empire.
This identity was formed based on a false understanding of history and excluded the Celtic Britons, as well as colonial subjects in North America and Asia. This cultural lag caused a division and exclusionary vision of white America.
On the other hand, England acted as a cultural borrower by importing goods from other countries through expanding trade, which helped to deepen the connection between England and its colonies and create a common identity among the colonies.
In conclusion, the cultural lag in England can be seen in the formation of an Anglo-Saxon identity in the 19th century, while England acted as a cultural borrower through trade and imported goods.
