Rubbish! While the US does it,
not all developed countries do. In the Schengen Area, for example, there is
no central database of entries/exits, however several Schengen countries do record entries/exits of non-EU/EFTA nationals in their national databases, which however can't be seen by other states.
As such, not getting a stamp there can very much be an issue, particularly if exiting through a state other than the one you entered through.
Regarding the topic, however, the US does record entries and exits electronically, so no issue there
