That is a useless definition in terms of policy.  We don&#x27;t care which legal profession people have.  We care about the value they produce and the pay they receive.<p>Class has vastly different meanings in the US or India etc. As long as the meaning was clear that should be enough for any reasonable person.  Especially when it&#x27;s a very common definition.  Whining about it is little better than trolling.<p>PS: The original definition of middle class even included working class people.  Working class people are not serfs and they are not aristocracy so by default they are middle class.  As the US got rid of slavery, has no real aristocracy, and calling everyone middle class is pointless, so the more reasonable definition <i>is</i> based on income.  It&#x27;s even been used in that context for 100+ years.
