What's up with blue collar workers looking like homeless bums?

And it's not because they can't afford a haircut or new threads either. Some of those guys make more than professional types, yet have mangled beards, mullets, and dirty hair that look like it hasn't been washed in months!!!

Is it symbolic and they're sticking it to the 'man'? Or are they mostly too lazy to care because they're out of shape and leather-faced?

It seems that these guys have three passions in life: fishing, hunting, and drinking beer till they pass out..
