LB- I made that point several posts ago- unless interst is added, the loan would not be paid at full cost tothe tax payer- might not seem much per individual case, but added over 1000s it would be.
I keep coming back to the same thing- the country does not- and will not have- in the foreseeable future, for generations, any spare cash for anything like this.
As has been said before, we all feel the same about banks and MP's expenses,but that is not a good enough reason to spend more on something like this. The money is NOT THERE!!!!
BG- from what you have said, it would not be impossible for you to fund the repayment from your joint earnings- you appear not to want to and think the system should be changed to suit your choice.
As VH has said, things change all the time. When my DCs were small, there were very few if any nurseries for young children where I lived- that is going back 20 years- and I took a long time off work as I did not want a child minder- only other option. What we lost in potential income from me is huge, and will always be so, as my pension is index-linked. Our lives now would be completely different had nurseries/more available childcare been around, or the financial help that is there for working parents.
However, it was my choice not to employ a child minder, just as with you BG it is your choice to have children whilst you have a loan to repay.
