Ultimately, what it really means..
..is these people are taking control of their lives, and their time.
We do not have a television. Do not miss it. I get news from 'net, and we have music, books, and conversation.
We tend to live pretty '50s ourselves - not in the sense that wifey wears an apron and cooks - I do the cooking and shopping - but in the sense of what we DON'T do - the only 'recreational shopping' we engage in is at Goodwill, we tend to do things that aren't mechanized, etc.
This is not a 'holier than thou' thing -- in my twenties, I didn't watch TV and was very strident about it. Now, I can see why folks like it, but I choose not to allow it in my home, believing that it disrupts my peace and is toxic. Others can certainly make equally valid but different choices.
I guess the way we are MOST fifties comes in as to how we arrange our home - we don't do carpets due to allergies. We don't wear synthetic fibers (much - my gym gear does have nylon in it) because they aren't comfortable, we don't have a big fancy bathroom that is bigger than a master bedroom was then, we don't eat processed food because of food allergy, etc.
And anyone who says cooking is a drudgery, has not done it my way. I can have a good meal cooked, start to finish, in under 30 minutes.
I DO have a dishwasher (though I suppose that WAS 50s) because it saves time, and it is quiet enough I am willing to allow it in my home.
I think it is important to have the kind of life YOU want - and if it is 30s, 40s, 50s, whatever, GO FOR IT!
