Not all areas in the UK have property available for £600. No less than £800 for a 2 bed place in Milton Keynes, rarely you might get one for £750 or so, and very often they will be £850 - £900.
Again this is doable, but after all bills and the likely cost of childcare or wraparound care you will only have enough for the essentials, it would take a long time to save any contingency money and you are constantly at risk of being one large bill, unexpected expense or end of tenancy away from being truly in the shit.
There is no need to be so judgmental about people's earning either, it's quite shameful actually. I am 24 and earn only earn about £21k, I would never judge someone earning less and especially women as it is often down to us to bear the strain on careers and be cornered into accepting low skilled or part time work to fit around having children. Don't have children then, you might say - but is it really right for that to be the only solution? And what about all the people who might have had well paying jobs but lose them or become ill? All sorts of stuff happens in life, and you're just being incredibly reductive and black and white. It's not always down to a person's "stupidity" that they are struggling. One huge thing that might effect them, funnily enough, is the huge overhaul to welfare that UC is. If you have planned a family on the basis that you have x and y available to you, and then that changes, is that really your fault?
