《The Hidden Lock-In Effect Driving the US Housing Crisis | Chris Bloomstran》
若经济恶化，DG可充当对冲工具，其驱动因素是中产阶级消费结构的变化以及SNAP使用量的上升。
但如果经济更早而非更晚地恶化，我认为它会成为类似艰难时期的对冲工具，正如Dollar General历来所表现的那样，因为它会迎来中产阶级消费模式的转变，以及SNAP（食品券）使用量的快速增加。
But if the economy gets worse sooner rather than later, I think it becomes a similar hedge for tough times, as Dollar General has historically been , as it gets a shift in middle-class consumption patterns, as well as a rapid increase in the use of SNAP ( food vouchers).
