After posting in favor of Africans, you've chosen to make us all aware of your contempt for ordinary Americans on account of their scanty general knowledge.

Nathan,it's time for English class.Bear with me,please!

Scanty means not enough for a particular purpose.For example,the fashion models wore scanty clothes,their partial nudity exciting the red-blooded males in the audience.The purpose of clothes here is to cover the body.
By contrast,scant just means not enough,no more,no less.
By using scanty instead of scant you have implied that the amount of general knowledge a person has serves a purpose.I'd agree with your chosen usage,and in my eyes the purpose is to prevent a person being looked down upon and considered a numbskull by others!
I reckon someone with a biblical forename has shot himself in the foot......LOL!

You'll note I've altered the heading of this thread to avoid ambiguity.The original heading "to work for Africans in China is rewarding" means if you work for African employers in China it is rewarding,obviously not what is meant.
That said,I reckon that you,Nathan,are American.That's why you're unhappy with the post you've replied to in this thread,ie that of Turnoi.
I must say that my limited experience of conversing with ordinary Americans confirms Turnoi's point of view on this matter.But of course I realise there are always exceptions.That's why generalisations are oftentimes controversial and divisive.Having said that,I don't agree with you that Turnoi has a hidden agenda against Americans.But that is a matter of opinion,and you are entitled to your own.
