IIRC the incubation period between exposure and first symptoms of bubonic plague is approximately six days, which would mean a determined walker could cover over 100 miles spreading his disease wherever he stopped to eat, converse, and sleep. Retarding that spread would be the fact that most travelers were not traveling any great distance. Serfs and peasants were tied to the land, seldom traveling further than the nearest market, but there were peddlers, pilgrims and couriers, as well as the upper classes and their servants, who were more mobile.
All things considered, two miles a day does not seem too unbelievable a pace if the disease was spread by human vectors. And yes, of course, railroads and steamships were the catalyst for the great nineteenth century human migrations and, naturally, their diseases.
Socialism doesn't work well in a society which publicly refers to their poorest citizens as trash, or differentiates between worthwhile citizens and said trash.

It's a good thing Oreos aren't as addictive as a drug.
Imaging if you took a hit of Oreos, got high, then got the munchies, ate Oreos, got high, then got the munchies, ate Oreos.... etc.
