Black Lives Matter (also?)

We, traditionalist Aristocratic Christians, support the efforts of BLM. We are simply a little confused that BLM has not yet given a specific dollar figure per black life that would, hence, justify the statement "Black Lives Matter." The cheapest new car goes for around $12,000 USD. Does that mean a black life is worth approximately $15,000? Slavery is justified in Holy Scripture and we devout Christians would like to seek to support BLM by purchasing many slaves as there is great work to be done on our estates!
