I could be wrong, but this reads to me like the author has strong views regarding gender roles. It sounds like he/she is suggesting that tobacco farming is a good, manly profession, whereas lavender farming is for effete task more suitable for women. As a consequence, a man who gives up tobacco farming to become a lavender farmer is giving up some part of his masculinity, and has therefor surrendered a part of his self-esteem. Obviously such a man would suffer damage to both his pride and his ego.
Nonsense really, the important thing to most farmers is that they get a good return on the time and money that they invest into a crop, regardless what that crop might be.
Pride - The pleasure one feels when contemplating one's achievements. The satisfaction that you have regarding your standing in society and the workplace.
Ego - Your sense of personal identity. How you see and judge yourself.
