It is hard for humans to visualize in their heads the difference between 1 billion and 10 billion. Our brains weren't created to think of such massive amounts of objects. I don't think it is too big of a social problem though.
It's probably because cavemen had to carry 10 rocks at a time, 15 max. We didn't have to use such large numbers until recently in human history.
