I totally agree with you. DH and I are both professionals, earn very good salaries and we have nearly cleared our mortgage after only 8 years. We don't believe in stuffing our house with clutter, we buy DTS clothes at bargain basement prices, shop at Aldi and plan to keep our car which we bought new with cash (£18k) until it falls apart.
I think society would do well to remember the story from the Old Testament about storing during the 7 years of feast so that when the famine comes, you have something to fall back on.
The live today, forget tomorrow mentally that has plagued modern society is just simply irresponsible fiscal, economic, social and political lunacy.
