OP, YABVU. In fact that's possibly the silliest suggestion on here for a while.
Being frugal means I have been able to give my ds a decent life.
I'm a single mum with no family support at all, but I've managed to pay for our home, ensure ds has everything he needs for school. Good quality shoes, warm clothes, home made food. I've sent him on school residentials and ski trips and paid for him to attend independent secondary school.
My average income over the last few years has been about £55k but I work it out. I watch every penny, grow as much food as I can, make my own bread. Keep my car at least a decade.
In the process I've also taught him not to waste money.
Now I'm working on how to get him through university without loading him up with ridiculous debt.
I don't hoard money, I make it work as hard as possible for myself & my family. My job is to do my best for DS. The economy can look after itself.
