Not from the US and not super familiar with dollar stores, so/but this was a fascinating watch. Terrible how they drive independent grocers out of business in small towns and their role in urban food deserts is interesting and horrifying.
I can't imagine having no access to fresh food. I live in a European city and in a 500 meter radius I probably have ten places where I can buy some sort of vegetable, fruit, dairy product, fresh bread, etc. Not to mention countless restaurants where I can also eat.
What I did wonder: in poor urban areas in the US, are there no small shops catering mostly to immigrants? In most places I've lived there are quite a few smaller shops that have products (including produce) from specific regions where many residents of the area are from. So like a Turkish bakery or some shop run by Colombians I sometimes go to that has plantains and queso fresco and stuff. I would think that especially in the US with so many immigrants you would have loads of those kinds of shops.
