There are layers to this:
1) There are different types of tests, for different purposes. Devs should be writing some of them. Other types & forms of testing, I agree that this is not in many dev's sweet spot. In other words, by the time code gets thrown over the wall to QA, it should already be fairly well vetted at least in the small.
2) Many, but far from all, QA people are just not skilled. It wasn't that long ago that most QA people were washed out devs. My experience has that while testing isn't in the sweet spot of many devs, that they've been better at it than the typical QA person
3) High quality QA people are worth their weight in gold.
4) Too often devs look at QA groups as someone to whom they can offload their grunt work they don't want to do. Instead, QA groups should be partnering with dev teams to take up higher level and more advanced testing, helping devs to self-help with other types of testing, and other such tasks.
