My father helped pay for my college (about half -- in-state tuition and some money toward expenses) and gave me a used car after I graduated. I truly appreciated the gift of starting out life with no debt.
My Dad told me when he was helping me out with college that I didn't have to pay him back, but he expected me to help my kids with their college someday. So, in the manner of "Pay It Forward", DH and I will be helping our kids with their college, will likely get them their first car (reliable used), and will probably give them generous financial gift for their wedding or first home purchase (my Dad gave my brother and I each $1000 when we got married: "Spend it however you want, but don't expect me to pay for anything else for your wedding.").
We will have DH's college (student loans) paid off next year. He paid for his first car on his own. In the past, DH's point-of-view has been, "I had to work for everything I ever got and so should my kids." But I've countered with, "But wouldn't it have made your life easier if you had been given more financial support."
My view, as long as the kids are working hard (paying part of car insurance, paying for gas, paying for spending money) and getting good grades at school and staying out of trouble, we should give them the support that we can (without suffering ourselves, of course). DH is coming around to my way of thinking.
Although, we do try not to spoil our kids too much -- neither DH nor I can stand the ENTITLEMENT that seems to be running rampant in so many teenagers and early-20s here in Connecticut.
