Right, but we had a similar suystem with our european standard, the main point is that if the child know how to use a screwdriver... its not safe.
These are still sold/used in old circuits with no grounding. (I feel pretty safe without grounding as far as it is no risk of touching any conductive surface that may lead to ground.)
In a new house alloutlets are grounded. (Schuko)
