Answer:
Uncle Sam
Step-by-step explanation:
Hello, the answer above is correct, and to elaborate as to why;
Given the topics, especially duty, taxes, nationalism and those of similarity, we would deduce that the best answer is Uncle Sam.
It would not be Teddy or Franklin Roosevelt, considering the description.
Furthermore, it would not be Canada, because of the description. The verbiage depicts America impeccably.
Hope this comes to your aid.
