Google search history privacy failure

Wouldn't it have made more sense to give access to individual, work-related Google accounts rather than all share one account to begin with?

The fault here doesn't even seem to rest on Google. The account can see its own search history. As far as Google is concerned the Google account is an individual and not a shared account.

Deleting history should be made easier, but is low priority. Few people know they can even check their search history...
