「列寧主義者」說斷言，美國的帝國主義政策產自美國商業精華區之共同利益，即必須確保並利用資本與貨品市場。自馬克斯主義者看來，商業行為之本質在於控制政府，國際軍備競賽不過是國際性經濟戰之一環，而兩者皆受資本主義固有之擴張天性所驅使。美國海軍退役將領史曼德雷·巴特勒（Smedley Butler）曾說他的工作是充當「大企業的打手」（"muscle man for big business"）時，即彰顯此種觀點。此說對帝國主義的典型解決方案為商業革命。此說於第一次世界大戰期間由布爾什維克、列寧，與布哈林，基於早期的馬克斯主義者、社會主義者、與無政府主義者的論點立說。阿里、福斯特、連司、與金殷諸人，連同史密斯本人，皆持此種看法，但各有不同形式。
布特其實肯用「帝國主義」形容美國的政策，不只用於20世紀早期，而是「至少始自1803年」。但這主要不過是用詞不同，布特仍辯稱美國對外政策向來基於善意。[37]布特並非個案，美國的保守主義專欄作家查爾斯·克魯瑟默寫道：「人們現正自『帝國』中一詞中出櫃。」（"People are now coming out of the closet on the word 'empire."）不少新保守主義者接受帝國一詞，如英國史家保羅·強森，以及作家汀許·狄守哲和馬克·史推恩。有些自由主義鷹派人士亦持相同態度，如齊畢紐·布里辛斯基和麥可·伊格納泰夫等政治人物。[38]

(原文"the United States would set up a constabulary, a quasi-military police force led by Americans and made up of local enlisted men. Then the Americans would work with local officials to administer a variety of public services, from vaccinations and schools to tax collection. American officials, though often resented, usually proved more efficient and less venal than their native predecessors... Holding fair elections became a top priority because once a democratically elected government was installed, the Americans felt they could withdraw." )
(原文："the United States was least likely to intervene in those nations (such as Argentina and Costa Rica) where American investors held the biggest stakes.

(原文："So influential has been the discourse insisting on American specialness, altruism and opportunity, that imperialism in the United States as a word or ideology has turned up only rarely and recently in accounts of the United States culture, politics and history. But the connection between imperial politics and culture in North America, and in particular in the United States, is astonishingly direct.")
