See also Snoopy's comments about "babyfarms". The point of this "advice", doubtless, is to encourage them to work in some way for the government - thus ensuring future votes. You won't get a pension that big otherwise and seeing as something like 50% of the sproggs born these days are expected to live to 100+, a good pension is worth far more to them than to us "older" folk whose life expectancy is probably a quarter of a century lower.
Utter, utter wankers.
