Market has gone up, too - if you're a recent hire, your comp targets are actually above those of your seniors. As an incoming L4 you can make up to 200k now, whereas 140 or 150 was considered 'good' 5 or 6 years ago. L6s who are pulling in mid 3s can leave and get 5-600k elsewhere very easily. It's not that the amazon money is bad per se, just that the industry and talent market are kind of crazy right now.
