I agree that 4 kids and the cost of 4 kids at uni is expensive....but you factor it into your decision making, as the fact they will all reach 18 and some at least will go to uni and involve costs is hardly a surprise.
Yes, it’s about choices which need to happen several years before and about prioritising. Essentially, parents who whose kids won’t qualify for the full maintenance (living) loan can choose to make some sacrifices when their kids are younger (cheaper holiday? Less frequent upgrade of cars? less spent on Christmas or driving lessons or extra curricular?) so they can give their kids something to fill all or part of the uni living cost gap, or they need to take on board that their kids will be paying it....and not via a loan (which isn’t available for that chunk of the living costs) but through needing to work themselves at that point.
Lots of people think it’s fine for their kids to have a few hours of work at uni and pay something, most would think that having to work significant hours at uni isn’t ideal as it will interfere with studies and the whole experience.
So most parents with the decent income Op has will choose to make some sacrifices earlier on so they can give their child something, even if not all of the gap that can be borrowed. They prioritise saving for this phase of their child’s life.
Of course some people with low incomes can’t save anything but those kids will be entitled to the full maintenance loan. It still has to be repaid and some working might still be needed.
It does seem pretty rough on kids from middle income families though, when their families say they won’t offer anything to plug the gap in what the child can borrow for living expenses.
I agree it would be better if all kids could borrow all that they need for the living expenses and it wasn’t means tested. However, I also think as a general principle that parents with decent incomes should expect to contribute something to living expenses and should financially plan to do this....but as said before, some don’t seem to realise the reality of what’s coming (lack of clear info available and also lack of checking it out themselves) and lots just don’t financially plan ahead, which is key to managing it.
