The Industrial Revolution decreased the value that society conferred on physical labor because it enabled unskilled workers to quickly produce goods that formerly took skilled craftspeople long periods of time to produce.
Evidence
The Industrial Revolution decreased the value that society conferred on physical labor because it enabled unskilled workers to quickly produce goods that formerly took skilled craftspeople long periods of time to produce.
Computations that once took skilled mathematicians a long time to perform can now be quickly performed by moderately well-trained high school students using computers.
Conclusion
Our most important intellectual skills will be devalued by electronic data-processing technology [similar to the way that the Industrial Revolution decreased the value that society conferred on physical labor].
Evaluate
The argument makes a significant leap by discussing mathematical computations in the evidence and "our most important intellectual skills" in the conclusion. Aren't other types of intellectual skills important? Aren't reading and logical reasoning skills, such as those tested on the LSAT, also important?
There might also be important differences between intellectual skills and physical skills, or differences between the Industrial Revolution and our current time, which would prevent us from devaluing intellectual skills.
