It's a bit more complicated than that...
Most of the Pakistan fixing problems were, IIRC, around spot betting. That'll be far more lucrative, and much less easy to spot, than throwing a five-day test match. From what I saw of the highlights Pakistan have just done an England and turned a winning position into a loss, via a bit of bad luck and some crumbling confidence.So, after a Pakistan victory looked likely after 1st innnings, Pakistan throw it away and collapse in their 2nd innings to lose a game they should never have lost.
A cynical person would suggest there could have been an element of match fixing. However, as Pakistan have never been involved in such a thing, it is unlikely to be be match fixing
