Gary Price mentions that Google has impressive benefits and only plans on making them better.
As I said back in July when Microsoft cut benefits, exceptional benefits are often valued well above their monetary value. Especially when the benefits are viewed as outside of the norm, it can be seen as gift exchange, creating more of a friendship than purely economic relationship between the company and the employees. Put simply, people care about a company that cares about them. It's especially important when much of your workforce could go just about anywhere they want to.
