The interesting thing here is: why do big companies don't need to keep their talents? Does bureaucracy compensate for lack of talent? And vice versa? Does this also mean that you can innovate without talent?
big companies exist to execute a well known business model. they invest in lobbyists to keep the business climate stable so they continue to execute their business model. it usually makes more sense to outsource innovation -- e.g., invest in and acquire startups.
