I think a lot of it is because parents these days increasingly have less and less time to adequately devote to their kids. Many of them just give in to the brattiness and let them do whatever the hell they want. Others try and placate them with presents or money in lieu of quality time that they don't have to spare, which in turn just makes the kids more demanding, more bratty, and makes them feel more entitled.
I think we notice this more in the gaming realm than elsewhere because, well, games cost money, and the children of parents who buy their kids every game that comes out tend to be more obnoxious and bratty than other children.
