Nothing, and that's great. Something I really enjoy about my current 250 people company is how many things are not arranged properly or at all. This gives me many opportunities to step up, identify issues and address them with management teams etc.

I had the opportunity to join Facebook a couple of years ago for much better pay and moving to the Bay Area (a long time dream) but decided not to do it for mainly the reason above, as well as alignment with the company mission (which is creating a product that solves problems, not creating free services and running ads like Google/FB).

Edit: "nothing" as stated above is a hyperbole. Actually there are many things that the company does or allows that make it a great place to work. What I like most is to help improving it further.
