Because in object oriented programming languages one tends to try to work
with the common denominator to ease up the dependencies between the
concrete implementations. E.g. the LCL relies on TComponent and TControl,
it does not need to know that there is a TMyWhateverControl. I even miss
inheritance in databases as well as that would make the tables simpler.
