Famous quotes containing the word plant:
“Do we honestly believe that hopeless kids growing up under the harsh new rules will turn out to be chaste, studious, responsible adults? On the contrary, by limiting welfare, job training, education and nutritious food, won’t we plant the seeds for another bumper crop of out-of-wedlock moms, deadbeat dads and worse?”
—Richard B. Stolley (20th century)
