It's not about them needing to find their own way. It's about teaching them the value of money, the need to budget to live within your means etc. At age 19 or 20 their brain isn't fully developed yet. They are still in the learning stage, they are still ruled by impulsivity and a bit of recklessness a lot of the time. When they are at uni they are in a false community - they generally are living with other young people in the same boat as them, not in a mixed community with different age groups, working people who need to get up early, families with young children, old people struggling on pensions, people living on benefits who have to use the food bank etc. They are not yet part of real life and a lot of the time they are living in student accommodation with all bills included. They have no real sense of how many hours they have to work to pay a month's bills, for example. How many times they can accept an invitation from mates to go out to the pub before they realise they have to rein in their spending or they'll have no heating next month.
We are comfortable financially and I am able to easily top up the expected parental contribution part of the student loan, and actually the way I give them money (I pay their accommodation) means they probably have more than a lot of students. But they absolutely aren't getting a massive lump sum of money from me yet to do with what they want. It would be an absolutely terrible, terrible idea. The money has for the main part stayed invested ready for when they REALLY need it, not when they want to spend it on shite at university and possibly get themselves into trouble with party lifestyles.
I will pay off their loans when it is financially a good idea (they are on different student loan plans and I have just paid the fees of the older one's 4th year rather than him take another year's loan as he has secured a very good graduate job and will be paying massively more over his lifetime than his original loan).
With the younger one, on a different plan, and possibly different earnings potential, I will probably pay off his student loan every month once he has started to pay it back (from money I have in investments for the purpose).
And they can both have money towards a deposit on a property WHEN they are at the stage where they aren't travelling around for work.
So my kids will get plenty of financial help. They are very lucky. They just don't need massive lump sums NOW.
