My experience tells me otherwise.

Correct.
However, if you invest enough time to make the code correct, you won't
have any customers anymore. They prefer buggy but early code to correct
but late code. And once the buggy code is out, they want even more buggy
code, instead of fixed code.
Correctness doesn't pay. Unless it's for free. (Which is why C is so
bad: making C code robust, not to mention correct, just costs too much.)


This depends entirely on the type of customers that one has, of course,
so YMMV.
