H. Beam Piper,
A Slave is a Slave
“ A slave only gets what his master gives him. But a free worker for pay gets money which he can spend for whatever he wants, and he can save money, and if he finds that he can make more money working for somebody else, he can quit his employer and get a better job.""We hadn't thought of that," Khreggor Chmidd said. "A slave, even a chief-slave, was never allowed to have money of his own, and if he got hold of any, he couldn't spend it. ”
