Seems like an odd way of going about it. If you and I work for the same company in the same exact job role but you're married to an unworking spouse with 2 children and I am single, I will be taxed higher than you so my take home salary would be less despite being paid identical amounts. You're destroying information by relaying it like this and it's misleading. Your personal tax situation is irrelevant to comparing salaries across jobs.

No, thats not what im talking about here.
