They beat on things with sticks, like a caveman. It's low hanging fruit.
The bass player often cops it to a lesser extent as well, it's how singers and guitar players retain our false sense of superiority. We actually usually love our drummers (but only if their playing is on form, otherwise they cop abuse).
Hard to find a good drummer. If you're in a developing world country, even harder because drum kits take up valuable space.
Pro tip: Having a hard time finding a good drummer? Steal one from another band. Of course, your band has to treat them better than the old band. This is a time-tested and proven stratagem.
(Agree with sibling posts, getting a great drummer is hard and amazing.)
