AMD64 and lib64

I'm totally amazed, totally ... who was the "smart" guy who figured out, that on a 64bit system, the native libraries should be kept in a non-standard directory lib64???? Every program I stumble upon, is choking on this ... they all try to locate their "normal" libraries in /lib or /usr/lib and expect them to be 64bit. How come, this "smart" fellow didn't put non-native 32bit libraries as lib32 and 64bit native libraries where every-goddam-thing expects to find them?
