Look, I'm going to catch flak for this but at the end of the day the main problem is that Java and C++, the most popular OOP languages, are just bad programming languages.

There are OOP languages out there, most of them older than Java and C++, that actually provide a much better set of knobs and handles for writing sane OO programs.

Java is finally getting a bit better thanks to a lot of market pressure and good ideas from Kotlin. C++ will probably be a mess forever.
