Not if you consider that 66% of the people who sit in congress are lawyers and they're only 0.36% of the population.

But a decent part of congress' job is around laws ( writing or sponsoring them, arguing for/against them, etc.) it makes sense that lawyers are overrepresented.

It would make sense that Congress hires a lot of lawyers but since Congress is supposed to represent the people I don’t think having one profession so heavily over-represented is beneficial. And I say that as a member of the heavily-over-represented profession.
