There are more important things than money to attract talented researchers. The cafeteria at IBM Research - Almaden [1] offered an "IBM Burger" [2]. (I had one, and they were delicious! A big hulking mainframe of a hamburger.) When Sun found out about that, they had their own cafeteria offer a "Sun Burger", in the hopes of attracting better qualified researchers. Cargo cult corporate research menu design at its best!
