@Twainfan2: On one hand, sanitation in 1918 was certainly worse, and there were still a lot of outhouses.

On the other hand, the US population centers in 1918 were not overran by shit-eating turd worlders that end up touching EVERYTHING related to all supply chains.

So yes, sanitation wise & infrastructure wise, we're better, but we're actually far worse population wise, at least in major urban centers.
