I wish they had used a different Restaurant for comparison. Pret is just not very popular here unlike in Europe and I don't know many people who'd eat there (except maybe to grab something on the go). Outside of Pret, portion sizes are usually much larger in the US so it make sense that lunch in general would be pricier. Plus European imports like Pret are typically located in pricey downtown locations of cities like NY and SF where real estate is very pricey.
