Houses were not all that different. Republican and Imperial Roman homes as well as homes from the medieval period onward were built to last for several generations and form the corpus of an ordinary family's inheritance, which would fall to the next paterfamilias in line. Not every house was Blenheim Palace, or even the Breakers, but ordinary families developed their properties for posterity and added to it with every generation.
Then came the Industrial Revolution, and the Middle Class was willed into being. Increased disposable income combined with mechanized manufacturing processes to create affordable facsimiles to traditional goods. Tailors began to disappear in favor of ill-fitted, machine-made suits; the vibrant, coach-built automobiles were replaced by standard body, standard color vehicles; the Old Fashion somehow acquired a cherry and Bourbon; and the unique, organic outlook on church architecture was supplanted by a cookie-cutter pattern: big altar wit the big six, Mary and Joseph altars on either side, and a plaster statue of the Sacred Heart.
McMansions, which create the most recent global recession, in that it provides immediate satisfaction instead of prolonged enjoyment by means of fakery. That's right, fakery. Just as a proper mansion (or peasant home, for that matter) has had numerous bricks re-pointed, wings added, copper and slate roofing, and changes perceptible from generation to generation, a proper church is an organic and living structure. A McMansion, on the other hand, looks like a mansion in that is has spires, pillars, colonnade, and cooper roofing, but on the inside it is replete with the most modern amenities, crummy furniture, and structural work intended to last no more than 20 or 30 years. It is a fleeting pleasure for those who want it and can afford it, not unlike our churches.
The McChurch model has changed considerably since the end of World War II. Mary and Joseph altars have given way to the only noticeable decor, the oversized Crucifix (or sometimes Resurrexifix). The Sacred Heart plaster statue has made room for Eucharistic adoration chapels, often with monstrous monstrances built into brutalistic tabernacles. Perhaps in an alcove, near the "Reconciliation Room", is an out of place oriental icon of the Theotokos. It is quite generic, ready-made, and unusable for an artistically inclined or growing community (unless the community wishes to grow by razing the existing structure for a new McChurch every generation).
Better yet, proper churches tend to roll over from generation to generation and are not viewed as disposable assets. Even Salisbury Cathedral, built for medieval Catholic worship and now beholden to Anglicanism for over four centuries, without a Mass since the reign of Queen Mary Tudor, preaches a better sermon on the Catholic faith than this or this.
