"Can to cain't" (can to can't) is an old Southern expression. Ask a pulp wooder the hours he works and he'll say, "I work from can to cain't."
They work six days a week and divide the seventh between church and the time it takes to repair worn-out equipment so it's ready to go again early Monday morning.
Can to cain't, he's always out workin'
Can to cain't, in the sun and the rain
Can to cain't, he comes home hurtin'
Got grits for his body
Cheap whiskey for the pain
Back at home there's a baby cryin'
Back at home there's a woman who cares
Back at home something's always broken
Back at home there's bills to pay
Men in suits always talkin'
Politicians and preachers, they always want more
Never worked a day, they never broke a sweat
Never been hungry, never been poor
Back at home the washer ain't workin'
Back at home the clothes line's on the ground
Back at home there's a woman waitin'
She knows her man will never let her down
But men in suits always whinin'
They never have enough, they're never satisfied
They never see the man who does the labor
He works all day 'til the day he dies
