Your teacher asks you to challenge me to give “one good reason why the law should not require that women be paid the same as men for the same work.”  I’m happy to oblige.  There are many good reasons, but I’ll here stick to one.

That one reason is that it’s practically impossible for government officials to determine when two jobs involve “the same work.”  What might look like the same work to outside observers – to government officials, lawyers, or even the workers themselves – might well be very different work.
