maybe there is a purpose to envy, perhaps it helps us to do better, to reach our goals.

maybe these men haven't got more than what you have got, perhaps that's just a perception you have due to low self esteem, perhaps it's not envy you need to work on, perhaps it's the way you view yourself. You're just as valid and important as everyone else, and it's a shame you think other people have significant advantage over you, but I'm also sure that this is just your perception based on how you view yourself.
