Comparison of American culture and Rome between the decline

People concerned about the decline of American culture often point out the similarities between the decline of Rome and the dec​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​line of America. Is this a valid comparison? Consider the following factors from your text as causes of Rome’s decline: the growing power and changing character of the army; the division of the Empire and the establishment of a new capital at Constantinople; increasing threats from outside, from Barbarian tribes such as the Huns and Goths; the weakening of the economy through increased taxes, monetary depreciation, and reduced international trade. Do you think this is a valid comparison—Rome’s decline and America’s decline? Why or​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​ why not?
