“Your post assumes facts not in evidence.”
Not all all.
Save for a few leftover fans of Adam Ant, no men are wearing powdered wigs, kickers with silk stocking, greatcoats and tricorne hats these days. Many do, however, live in homes decorated with bombay chests, wainscoting, and crown moulding right out of Monticello, if not Versailles. And how many ladies wear petticoats, hoop skirts, and bloomers anymore?
Now, I ask you, if you go to your local car dealer, just how many new vehicles, other than a few trucks, have floor boards or suicide doors? Pontoon fenders and exposed exhaust pipes?
Just how many MP3 players can you find at Fry’s that are as big as a small safe, with an arched cathedral style cabinet, large bakelite knobs, and vacuum tubes inside?
It is readily demonstrable that style and design in almost every other area of human technology has changed radically over the last two thousand years. Except for architecture and decor. The same styling cues and motifs have been recycled ad nauseam, and not always with the greatest of dexterity.
How long does a set of clothes last?
How long does a house last?
If I want a set of clothes that looks roughly the same as that of a few "generations" of clothes ago, I can get that. And it's not uncommon for folks to want that. It's certainly available.
If I want a car that looks roughly the same as that of a few "generations" of cars ago, I pretty much can't get that.
If I want a house that looks roughly the same as that of a few "generations" of houses ago, I can get that. You seem surprised, or annoyed, that folks want it. Why?
If I had wanted to, I could have bough a house that was actually built in the 1700s. The market for such is very tight ... yet you're shocked (or nauseated, or whatever) that folks want to build houses which echo the actual colonial houses.
The continued popularity of Medieval, Renaissance, Baroque, Romantic, Classical, Folk, etc. music should be a clue to you.
The continued popularity of Iconography, Medieval, Renaissance, 17th & 18th Century painting should be a clue to you.
"Modern" isn't necessarily good (in fact, much of it is very bad.) Old isn't necessarily bad, and much of the "bad" has been left in the famous "ash heap of history".
Would you actually want to live in a house like "Falling Waters" ... relocated to, let's say, a 1/2 acre lot in Fairfax County, VA?
(Full Disclosure: Even in its actual location, I think Falling Waters" is incredibly ugly.
