Ugh. I hate the whole 'my parents don't have enough money to pay even though they earn £50k'. In America a lot of parents put money aside from the childs birth for their tuition fees!
It makes sense...there is not enough money to go around.
So the parents who have the capability to paying towards maintenance, are expected to contribute. The parents who have nothing, are not expected to contribute.
Children are for life and for certain I would consider whether I could afford to put my future children through education before even trying to conceive them!
It's unfortunate that some parents put a big house, holidays, Sky TV as a higher priority than their childs education.
