I think it's on HN because such salaries will hunt talented or not even good engineers down and if this happens it could be a really hard time for startups. Let's be real for a second without engineers ideas are worthless and if all of those good ones are at big companies which gives a out a lot of cash what can you do as a startup? I don't it is bad as it sounds but it could be tough and it could kill a lot of startups in future if this attitude by big companies grows.

In the contrast: you don't have to start your company in the Valley to be good and maybe it can save you a lot of headaches and money to not do so.

But at the end the source of this problem is different: the Valley just needs more engineers to get things rolling.
