Why were slaves needed so much and why were they so expensive?

Thank you lord lord please thank you lord lord for that you please thank you lord lord thank lord for that

As per my perspective I would say firstly it was a trend; secondly at the times of oppression/ignorance rich ppl had nothing good to do else than enslaving and showing off their power, comparing it. They were mind sick and had no idea of right and wrong like at the times of Pharaoh.

Now ur 2nd question is why were salves so expensive because discrimination was immoderately high. The rich ppl were richer and vice versa.

HOPE IT EXPLAINS !!

A. democrat, republican, whig, other.(the democratic and republican parties are the main 2 american political parties, the whig party was popular among the early presidents, and the “other” option allows for outliers)
