Around 26% of toys bought at Christmas are neglected by the end of January, and 40% will be thrown out within the first 3 months of being unwrapped. Combined weight of electronic toys comes to 3.2b kg

Sure, but gift giving is supposed to be about showing that you care and cash generally is a poor vehicle for that. Buying a plushie of their favorite YouTuber that they can't shut up about proves that you do listen even though you often say "that's great honey but can you please put on your shoes so we can get to school on time today?" while they're mid sentence.

The waste really comes from the gifts that target the age group (and gender and other demographic attributes) but not the individual. My son got an electric race track that he'll use max two times more before it will end up in storage and forgotten, because the uncle that gave it knows his age and that he's a boy and little outside of that because he's not engaged and part of his life. He just happened to visit on Christmas this year.
