I think there is a deeper issue here with immigration labor. The only one's applying to work at 7-11 or a lot of these minimum wage jobs are people who are not dependable or are immigrants without the proper paper work. So if you hire the non dependable worker you are going to be going through the hiring process every 3 months.

Most people you'd like to hire often say "Why would I come work for you when Uber pays me X?" Uber has made it a lot harder to find dependable workers for convenience stores because most stores aren't willing to raise the wage so high that would eat away into their profit of owning a store in the process. I'm all for fair wage practices but at a certain point you'll be seeing a lot more 7-11's for sale than people willing to buy them. The economics will stop making sense to purchase convenience stores or rather start many small businesses because the wage to pay out will be too high.
