One of the most maddening things for many evangelicals and fundamentalists is the culture of getting things "as cheap as you can," and I'm afraid it stems from a basic confusion of the concepts of "thrift" and "cheapness." Contrary to what we often believe, they are not synonymns. "Thrifty" people conserve their resources by appropriate purchases of quality items at a good price; "cheap" people squander their resources on shoddy, "cheap" goods.
What's the cost? Let's start with shoes; you can save a lot on 'em if you go to Target, right?
Well, run a few miles in 'em, and let's talk about how much it costs to go to the podiatrist. (personal experience) If you're lucky, it'll be just your feet and not your knees (orthopedic surgeon) and back.
Increasing numbers of us aren't so lucky. What is thriftier; $100 for a decent pair of shoes, or $500 in podiatrists' bills, or thousands for knee or back work? Those $20 shoes were cheap, but they sure weren't thrifty, were they?
Going further, how many people never get in shape because they never get shoes that fit. Now think about medical costs of $6000 per person annually, and half that due to lack of good diet and exercise.
Now how much are those cheap shoes costing you?
