I honestly cannot believe someone would spend so much money on an 11 year old for their birthday! I do not mean to offend anyone that is in a financial position to be able to spend that sort of amount, but how is that meant to teach kids anything about the value of money?
When I was growing up, even as a teenager, I knew that my parents budget was around $50 for a birthday and $100 for xmas presents - so I knew what was reasonable to ask for when it came to gifts. That was pretty average amongst my group of peers, and I wouldn't have said that any families I knew were poor. I'm under 30 too and I do not believe prices have inflated that much that kids could reasonably expect to have $200 given to them for a present at that age.
My DH spends approximately $100 each for birthdays for his two sons, but they are 16 & 18, so I think that's reasonable - anything more in my opinion is excessive and wasteful.
If you don't agree with me, that's fine, but please consider for the kid's sake, just how many hours they would have to work at an average teen job (e.g. McDonalds or Woolworths) to earn that sort of money? If it's more than they could SAVE in a month (after paying for personal expenses like a mobile phone, public transport, sports fees, school lunches, etc) then they are more likely to run into credit issues and massive debt in the future because they have a skewed sense of monetary value. If you must give such large amounts of money, as a PP said - encourage mandatory saving of most of it.
