Societies are dynamic and diverse, and they are subject to laws of cause and effect.
Your statement that you choose to keep your money in a shoe box and that you refrain from investing in the stock market because you do not believe in capitalism leads me to conclude that you have chosen to behave in a way you think honorable. Your decision not to have sex without pleasure suggests to me that you have chosen to honor yourself. Both of these acts seem to me to honor life and to acknowledge that your choices have meaningful consequences. Your statements indicating that you are unrestricted by structural forces and that you have no desire or hope to change the system seem dishonest to me. I wonder if they actually reflect a refusal on your part to own up to your enormous privilege in the world as a Brown student.
