… is from page 403 of the 1973 Oxford University Press paperback edition of the late economic historian Jonathan Hughes’s vital 1965 volume, The Vital Few (emphasis added):
[Y]et it is important to recognize that “history” is what the historians say it is, and in this case, the history of 1870-1914 is very largely what the muckraker historians said it was. That the period which saw such enormous economic growth should become known mainly as one of constricting monopoly is paradoxical to say the least. To say the most, is to say that both cannot have been true. Nevertheless, the muckrakers have been victorious.
