...we wouldn't have to return to the unsafe cars and now-primitive electronics of the time, let alone the awful cuisine.
You mis-remember the past pbrower. Cars were at their safest in the 70s and 80s - can't beat
mass in an accident - just add a seat belt. As for electronics, they're overrated. Most of the technologies that best-improved our standard of living and were the most useful overall had been fully developed by the 1950s. What's come along since has either been electronics/computers, or just been slight tweaking of the real innovations of the first half of the 20th century.
Finally, I can assure you that the diet of
most Americans was far better in the 1950s than in the present day - the simple fact that farming and the restaurant business were less dominated by large corporations explains this.
