"My" approach is just the chip-in. The allowance system is what I ASSUME most people use (the one the article is advocating). I'm surprised the author thinks it's novel.
I agree on budgeting and bookkeeping. Frankly, we do neither. I buy a bigass TV because I want it, my wife buys some awesome workout gear because she wants it. It just works. But yes, it's a position of luxury to not have to budget.
FWIW My SO and me are the only people I know who do the allowance thing. My friends routinely talk about "he/she spent so and so much on $USELESS_ITEM, grumble grumble". I say "pocket money!" and they nod and laugh and don't do it because it makes them feel like children.
You have to decide on your priorities. Accepting a certain amount of “waste” in exchange for happy spouses is a worthwhile trade for many couples, including my wife and me.
