I look at it this way.....
I get paid to work in waste water treatment plants now, walking in shitty piss water all day. I get paid a LOT less than that now, so if all I have to do for a HUGE raise is have a pissing alarm clock or a chesty steamer then the rest of my day is free and clear, I'M IN!
If you want to think you are better because you won't, fine. But when your shit chugger of a toilet breaks and the local plumber can't come fix it for you, have fun playing in shit water for free. Not everyone can be a CEO and some people don't mind earning a living by getting dirty. Just because someone doesn't mind getting that dirty, doesn't give anyone the right to look down on them. Someone has to make the shit, someone has to shovel the shit.
