This is the line I have a bit of trouble with. You shouldn't try to bring others down to feel better about making more, you should see what they're being paid and realize you are worth more. Outline this in asking for compensation adjustment, or begin to look elsewhere. If you can't find a role making more, just try not to let what others make bother you. At the end of the day you are the only one looking out for you - so invest more in doing that, and try to spend less worrying about others. Their making more or less will have little to no impact on your personal career progression.
