Most people who read financial articles understand why dollars are generally used though no matter what their local currency is.

American books are probably not Anglicised because we can still understand them, the UK is a smaller audience so no financial benefit, and the costs involved in doing a find replace then proof reading it to ensure no grammatical errors.
Conversely, if they had to replace philosopher with sorcerer anyway, then with the larger audience, it's more likely to occur the other way, with English books being americanised.
It would be down to the local publisher though as they would foot the bill for it.
