They will pay us what we negotiate. The Public perception battle that we want to win, starts with us being consummate professionals inside and outside of the cockpit. That means wear that darn hat, tie that tie, and polish those shoes.
That irks a lot of guys, but it you show that you are willing to take care of yourself, you are showing some accountability, when you choose not to, that is where we as a profession have an issue.

You will never get paid what you are worth, you will get paid what you negotiate. Hence the reason for a Union/Association in this profession. Seniority abrogates your portability and the ability to move to the next best paying job like Doctors, and other Professionals do.
