I think if anything it tells youngsters that it is not worth selling your soul or cutting corners for a few fast illegal $$$. Had they not been caught, each would have gotten a few £1000 at most… right. apart from great badnaami and shame of course.
On the other hand had Amir & Asif been playing regularly during the time they were banned they would have had 250+/- and 350 +/- test wickets respectively by now and been millionaires in £ in their own right. Asif is already a millionaire (in Pak Rupees at least). Was reported at the time to have 2 or 3 houses in Lahore alone.
