Think of it this way. If you can get away with so little work while being recognized as a solid contributor, you must be extremely competent: where a newbie sounds the entire day on busywork to find a solution, you just see the solution and spend the rest 7 hours reading HN. Also, when was the last time your manager approached you with a conversation "hey, out company is doing much better, so we wanted to double your pay and give you this expense card to pay for flights, hotels and restaurants, wherever those might be"? The company isn't seeking an opportunity to spend more money on you, so you should be doing the same. It's just a business relationship.
