Many years ago now, back in the days before the labourers' transport to and from work was upgraded to busses, (the old semi-trailers were pretty awful, if not quite "cattle trucks"), I recall commenting to my wife as we drove along behind one such truck full of dull-eyed (i.e., exhausted) workers, that if one day, one of those fellows was to get literate enough to write a book about his experiences of Dubai, we, comfortable in our 4WD, might find ourselves squirming.
The article might descend into hyperbole on occasion. I'm embarrassed to say I can't comment on the accuracy of its description of the labour camps, but suspect it's not too far from the truth. However, its description of the behaviour of a some expats, (see the description of the evening at "Double Decker", and the comment re the young Dutch woman and her inappropriate mode of dress), it's distressingly close to the mark.
