I usually try to avoid political stuff on this blog, but the following I think is worthwhile in terms of Christian theology. Fr Tim in Sioux Falls tipped me off as to two bills that have been introduced in the South Dakota Legislature that are aimed at tackling usury and "Payday" lenders.
Those Advance Payday loan/lenders are truly creepy organizations that prey on poor people. While some are probably somewhat more ethical than others, I have had to help parishioners at a previous parish who got sucked into those types of places. They are not quite the Mafia, but some of them are quite close.
If you live in South Dakota, please consider talking to your legislators to support efforts such as this.
