The running joke is that American legislators make "surprisingly" good stock trades for "reasons." Regardless or not of whether these picks actually tend to be good long term investments, it really, really rankles to know that a legislator expects poverty to come, is banking on that, but is otherwise not telling diddly squat to her constituents.
Dollar stores are the stores that sell the absolute cheapest versions of products. Usually low to very low quality, but when you're tight on money, it's where you go. If we enter a recession or depression, those type of cheap stores are going to get a lot more shoppers as folks try to tighten their belts.
