“In addition to the Catholic Church’s ban on contraception, a ban which had added force because of the religious cohesion of the ethnic neighborhood, one of the main things which fueled this demographic increase in Philadelphia was the rowhouse. It was cheap enough for a worker to own. It was more spacious than an apartment, and instead of paying rent and being at the mercy of landlords, a man could own his home free and clear in the time it took him to pay off his mortgage. Since it was located in the city near public transportation, the rowhouse did not require the expense of owning a car. Since it was surrounded on both sides by other houses, it was cheap to heat. As a result, it allowed the working-class Catholic family to have a large family, and over a period of time, it allowed him to benefit from the political power which followed demographic increase, which is precisely what was causing Blanshard and the Phillips crowd concern.

The attack on the rowhouse which the Better Philadelphia Exhibition orchestrated meant an attack on all of the cultural attributes that went with the rowhouse, a building which symbolized the cultural independence of the ethnic neighborhood based on religious cohesion and the economic independence of immigrant workers who could own their own homes. The attack on the rowhouse in Philadelphia was a covert attack on the Catholics who lived in them, orchestrated by a ruling class that knew, as good Darwinians, that demography was destiny and that they, because of their all but universal adoption of contraception, were on the losing end of the demographic equation. Urban renewal, like the sexual revolution which followed it eighteen years later, was the WASP ruling class’s attempt to keep “the United States from becoming a Catholic country by default.”
