there's a big difference between taxes and protection money, taxes are based off of percentages usually from a person's worth or earnings, where as sloane's fees are flat and ever increasing, and some people here have said that the exiles are all blood thirsty killers who were actively involved in the nexus uprising, this actually isn't the case, quite a few exiles were barely involved, and not really by choice, and it seems quite a few of those people were kicked off of sloane's oversized hill.
i don't really trust reyes, but i find him far more palatable than sloane in almost any regard. and i'm not found of being forced to have her back in that meeting, even after being pretty clear about my dislike of her and her outcasts thugs. and honestly the entire time i was on kadara i was looking for a way to off her without starting a war with the exiles, or a bloody power vacuum.
