@spendius,
These are deep waters, Spendy.
There was an opinion expressed at my class tonight (by a mature working woman) that plenty of unmarried mothers of her acquaintance had their babies just so the council would give them accommodation, and have no intention of ever doing anything other than having children and collecting benefits.
Then there was the European politician recently who said the immigrants were out-producing the natives, the wrong people were having too many children, and the nation was becoming less intelligent as a result.
Are we diluting our stock? Are we giving money to the undeserving and the feckless?
