I am not on Facebook, but my wife is. According to her there are countless posts from women complaining that their husbands / boyfriends are wasting their money on sports betting.

So while it's a small percentage of GDP, it is a much larger percentage of their budget.

I am Facebook friends with a lot of women and haven't seen a single such complaint. That's obviously not a real population survey but if it was really a widespread problem then I think I would have seen it.

I'll have to ask her, but I'm pretty sure that this is in closed groups and not people posting about it on their wall.
