Why? It is already happening with "mid-century modern"...I lost count of how many dumpsters I filled with "mid-century modern" appliances and fixtures while working for a general contractor re-doing kitchens/houses in the late 80's and early 90's. Now, there are whole industries around restoring and refurbishing what used to be considered trash. The time period is marketed as a high point of American quality with things being "built to last" and Made in the USA" and "repairable, not disposable" (sound familiar? cough.. C&V... cough) Its an endless cycle. Average becomes valuable as time goes by.
