If everyone's giving everyone the same gift, it's not really a "gift" any more, more of a p2p buy-now-pay-later arrangement (which isn't a terrible idea, but it's suboptimal for those with later bithdays).
Might as well just have an annual theme and try to negotiate a bulk discount.
it's simple. if i were part of an economy, we would all just act rationally. that way everything would be efficient
Not everything needs to be optimized. Probably only rich people would engage in such a scheme anyway.
Yeah this pretty much just a “tanda” except everyone pitches in to get the battery instead of paying out to the birthday person.
