A white girl trying to seduce a black man especially during that time period was a huge no no. Her father beat her and put the blame on Tom as no one would say anything.
Polgamy includes large number of family members so its easy to live by relying in agricultural methods than to buy food from the market. I hope that this helps you Sir or Miss :)
