As technology progresses, products generally become cheaper to produce. We only have to look through history to find some examples. The moving assembly line helped make producing a car much more efficient, and therefore cheaper. Televisions with screens smaller than a ruler used to be an extreme luxury item, and now the average welfare recipient owns one the size of a wall. The same is also true for computers. What once was a machine relegated to a privileged few at a university now is so cheap that kids in third-world countries have them.
There is some technology that we pay an awful lot for, even though it is actually very cheap. Listed here is the top tech that we as a society greatly overpay.
