Let's say we all go to the movies. And they say, Eric, your ticket costs $7.50. Jeff, since you're not married but you're working, your ticket costs $12. Matt, since you're only working part time, your ticket will be $3. Likely, Jeff would be mad that Matt gets in for a quarter of his ticket price just because Jeff has a better job. And that's why uneven taxation with completely uneven distribution ticks people off.
