[Futurama]In Futurama robots are generally sentient, self aware and able to reproduce. However they are still sold and owned as property. How is this not slavery?

The Professor on several occasions mention he owns Bender and on several occasions Bender is mentioned as his property. 

We also know that robots are able to reproduce, are sentients and to a certain extend (after an upgrade) have free will.

When looking at the definition of "Living" on Wikipedia we can see the following

Biology
Since there is no unequivocal definition of life, the current understanding is descriptive. Life is considered a characteristic of something that exhibits all or most of the following traits:

1. Homeostasis: Regulation of the internal environment to maintain a constant state; for example, electrolyte concentration or sweating to reduce temperature.
1. Organization: Being structurally composed of one or more cells — the basic units of life.
1. Metabolism: Transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism). Living things require energy to maintain internal organization (homeostasis) and to produce the other phenomena associated with life.
1. Growth: Maintenance of a higher rate of anabolism than catabolism. A growing organism increases in size in all of its parts, rather than simply accumulating matter.
1. Adaptation: The ability to change over time in response to the environment. This ability is fundamental to the process of evolution and is determined by the organism's heredity, diet, and external factors.
1. Response to stimuli: A response can take many forms, from the contraction of a unicellular organism to external chemicals, to complex reactions involving all the senses of multicellular organisms. A response is often expressed by motion; for example, the leaves of a plant turning toward the sun (phototropism), and chemotaxis.
1. Reproduction: The ability to produce new individual organisms, either asexually from a single parent organism, or sexually from two parent organisms.

Most robots in Futurama meet all of these criteria.

So how is this not slavery?

Zapp Brannigan sent a ship full of children into battle against the scammers. Humanity knowingly devoured Poplars by the billions even after discovering they were intelligent babies. Earth isn't exactly fond of any being, whether it has one or more souls or fewer. 

Life all kinds is cheap in the future. You can xerox personalities out of immortal heads. People can be cloned from skin growths. And the universe is pretty much always about to end for some reason. 

So who gives a shit about robots?

Basically we're going to pave over this question and get on with our lives.
