I'm afraid Gentle Giant's description and figures are an example of cherry picking from the kind of information in the pages of the Daily Wail mousethief

In Feb 2010 The Daly Mail reported that
"The proportion of mothers who bring up their child alone has risen from 10 per cent to 25 per cent in the past 20 years.
At present, there is no tax incentive for mothers to marry the fathers of their children. A report into the findings for centre-right think-tank the Centre for Policy Studies said there is growing evidence that
'lone motherhood is less a result of relationship breakdown, more a lifestyle choice'.

However it goes on to state for those with the attention span to read that far that

"Around a quarter of all children grow up with a single parent, and a high proportion live below the Government's poverty line."

Hardly the picture of single parenthood as a "well paid profession"?
