It's worth separating out the packaging waste in statistics e.g. if you buy a plastic doll in plastic packaging, the doll might account for most of the plastic.

If you buy a plastic lawn chair there may be no packaging, but still a sizeable lump of plastic.

Package recycling (and reclamation) rates are surprisingly good, even in the US which you'd think is culturally incapable based on the anecdotes you hear. It seems like big cities where lots of people live are doing better than less dense areas where relatively few people live, which keeps the stats high.
