People have more money than time. It's that simple.
I've just had to pack up my collection again as we're moving out of the city. Happy to do it and I won't be downsizing for the sake of downsizing—ever, if I can help it.
I love wandering through and re-reading things I'd put aside for some time. Poetry, in particular, is good for that.
I think it’s more that people have more interests than they ultimately have time to concentrate on.
Me, I have a kindle and have read everything on it.
