What did Abdu'l-Baha love about America and Americans? Did he love captialism, with its focus on a drive for profits? No he loved the potential that he saw in each American citizen. Here is what he inspired his grandson to write in The Advent of Divine Justice.
"The glowing tributes, so repeatedly and deservedly paid to the capacity, the spirit, the conduct, and the high rank, of the American believers, both individually and as an organic community, must, under no circumstances, be confounded with the characteristics and nature of the people from which God has raised them up. A sharp distinction between that community and that people must be made, and resolutely and fearlessly upheld, if we wish to give due recognition to the transmuting power of the Faith of Bahá'u'lláh, in its impact on the lives and standards of those who have chosen to enlist under His banner. Otherwise, the supreme and distinguishing function of His Revelation, which is none other than the calling into being of a new race of men, will remain wholly unrecognized and completely obscured.
