I do not know the answer, but if I were to guess, that it would be the one about plantations.
Plantations were hotspots of manual labor, specifically slaves. And when slaves were outlawed the plantation owners lose there main source of “profit” (aka the need to not pay workers for manual labor and instead use that money to get more laborers) it seems like the logical answer to me.

King George III is the answer
