You must be going to different MKs than I do. My experience is the MKs have always had (at least since Dec 2008, when I started) plenty of seasonal fresh fruit, pre-made salads and sandwiches in addition to the dried cereals and pre-packaged snacks. <shrug>
The perks are nice but are far from the top of the list of things that I would miss about working here - working with world class people, the opportunity to work on huge problems at scale, the amount that's invested in internal tools and processes, a culture that allows and even encourages you to question management - those are the types of things that I would miss.
The perks are just nice extras.
