A good QA engineer is worth many multiples of their weight in gold.
I often find that devs who think otherwise have never had to ship anything against a drop dead date, or definitively prove that a supplier has not met a contractual obligation (after the normal engineers have found it to be their problem in the first place).
I think I agree with your first sentence but opposite to the second. People I've met who don't prioritize QA (or test, reviews, etc) often only shipped with a mad dash towards a schedule is king deadline. Only on times where we can slow down and do things right do they appreciate the investment and its resulting dividends.
