I don't know the whole story, but I think the mistake was storing the toys at your workplace. Once it is out of sight, it's out of mind so those toys you've stored away don't exist for your wife or your kids. So your perception of how many toys your family owns is much more different than the rest of your family. Maybe bring all the toys back home and see how they react. Either they realize it takes up too much space and discard it themselves or they are fine with it and you just need to work on disregarding your negative feelings seeing all those toys at home.
