self-service checkout machines in THE GOOD Posted 14 May 2005 · Report post I think the self-check-out lanes are a great idea.First, I can scan my stuff quicker than most people at any of the stores.Second, it brings down the total cost of prices which in turn makes my life better. I have more money to spend on other values.Lastly, the lines are always empty in my local Wal-Mart, which means I am in and out as quickly as possible. Again, this enhances my life because my time can be spent in other areas. Economics is defined in many ways, but I use a definition I once read (I can't remember where), conservation of ones resources. This does not just mean your money, but your whole life. Anytime I can get something of the same or like quality for less effort, it allows me to use that effort in another area. This is one science that a lot of people under-value in their own life.←You probably think that Jim Taggarts idea to remove diner cars was a great example of conservation of resources. Maybe we should require fast food customers to clean the bathrooms. Then this savings could be passed on to the customer, instead of being wasted on hiring a person to clean the toilets. Heck I bet you can clean toilets faster than most people.
