"If a person invests in any form of property - a farm, a building, a ship, a horse, a tool, a slave - then he expects to receive from its use more than he paid, but over a more extended period of time. All such investments carry some risk. Blight, fire, wreckage, disease, rust, escape. This is normal and a savvy investor expects it. I would have much more muted objections if there were some particular slave of some elevated importance it would be politically expedient to seize. You would ruin only one man's fortunes, if that.
"If every farm in Cheliax fails at the same time - every building collapse, every ship go under, the horses all fall to a novel horse pox, rust monsters hatch out of every nook and cranny and devour all the steel? Then that is a catastrophe. We are seeing something like it in the wake of the failure of the Asmodean priests; little missed they may be, but people are falling to cholera and thirst in every area that does not enjoy the regular visit of another sort of cleric. One priest disappears? One village fails, or imports a new priest. All of them? You see the problem.
"If you must destroy all industries and households which at present rely on slavery, as I acknowledge there are many sympathetic reasons to do, you must do it in a way which insulates the economy from the strain. You must pay for that which you take. Else it will be like turning locusts loose over the fields. It will be impossible to hire the simplest of labor for less than what we are making here at this very convention. Trash will not be collected and rats will breed in the cities. Mines will close and our ore industry crater. Crops will rot in the farms and people will go hungry - ordinary people who could never have afforded their own slaves to begin with."
