本質就是美國的經濟長期發展，好過世界上其它任何一個國家。過去200+年的曆史，一直驗證這是對的。
巴菲特強調過：
"In its brief 232 years of existence ... there has been no incubator for unleashing human potential like America," Buffett remarked in an annual shareholder's letter. "Despite some severe interruptions, our country's economic progress has been breathtaking. Our unwavering conclusion: Never bet against America." -- W. Buffett
巴菲特在年度股東信中指出：“在短短的 232 年曆史中……沒有一個國家像美國一樣，能夠釋放人類的潛力。盡管經曆了一些嚴重的幹擾，但我們國家的經濟進步令人驚歎。我們堅定不移的結論是：永遠不要看空美國。”
