I see a similar issue in my line of work. Many of the programmers (even
those working for the larger software houses in the social housing sector)
have started out their careers as housing offices or maintenance surveyors
or whatever and have drifted into programming over the years. Their bosses
(in fact, in some cases they are the bosses) demand database neutrality so
they can run with whatever DBMS the client prefers and they simply take the
simple option and include all RI and other constraints in the client or
middle tier, partly because they don't know any better, but more these days
because they don't get the time or resources to do the job properly :-(

You can imagine the fun we sometimes have chasing down data errors!
