The benefit of object-orientation is message dispatch. Objects are peers.
They define what to do, not how to do it. Delegation of responsibilities is
therefore way more dependable a concept than simply polymorphism. If the
notion of a network of inter-cooperating agents working together to accomplish
a task resembles your task, then objects might make sense.
Polymorphism isn't why object-oriented frameworks are successful. In general,
frameworks are successful because the problem application domain was well
understood before it was ever translated into code. Frameworks tend to address
a vertical line of business (some ill-defined problem application domain) or a
horizontal line of business (i.e., security). Frameworks are also successful
because they usually glue together off-the-shelf software in interesting ways
that rapidly solve problems.
Also, if you want to make your code to be very simple, then just obey the
first rule of programming: figure out what you want to say before you figure
out how to say it. Meaningful abstractions can never be crafted in the absence
of a well-defined context.
Programming language concepts don't make programming simple. Deep, penetrating
knowledge of the problem application domain makes programming simpler. Having
a language that you can easily translate that knowledge into is also a boon,
just as having off-the-shelf software that you can glue into your architecture
is a boon.

OOP provides one major benefit - polymorphism. If you don't need
polymorphism, you should not be using OOP. But in some cases
polymorphism can make your code very simple and yet highly extensible.
It *can* be extremely powerful.
