The difficulty in this problem is possibly your concerns that by letting your boss know that you recognize this that you may jeopardize your job. The thing is, if you do confront your boss about this then s/he will be forced to take responsibility for his/her actions, which clearly is difficult for your boss since s/he is stealing your ideas. My suggestion is to be on the hunt for another job that will allow you to benefit from your wonderful ideas that way if by telling your boss your concerns it does create a hostile environment at least you can happily pack your bags without remorse for speaking up. Also, report your concerns in writing so that if possible you can consult "higher ups" about this should the work environment not change or become too hostile.
Ever since I can remember, people, stranger and friends, have always felt comfortable telling me about their personal issues. From these people I have always gotten feedback that I should be a therapist. As a result, these experiences led me to obtain a master's degree in Marriage and Family Therapy from the University of Southern California and to pursue a career as a family therapist where I have had the wonderful experience of working with children, families and couples with a diverse range of issues for nearly five years. I feel that this work has touched me in so many ways and has helped me to grow in my wealth of knowledge about working with people to address the toughest of issues. I have seen many people go on to resolve severe crises and to become successful in navigating future difficulties in a range of situations and settings. I have been lucky enough to feel completely rewarded by my experiences so much so that I feel compelled to apply as an advice guru for GMA. I watch the show every morning and would love to be a part of the team so that I may make a valuable contribution and place my unique stamp on the world. Thank you for your time and consideration!
