Not, if your PhD is in something mindless, like political science.
OTOH, there's not a lot of places where a PoliSci Ph.D. would substitute for industry experience (or, for that matter, vice versa.) If you want to substitute an academic degree in that general space for “industry” experience, you go for public policy and/or public administration (or, arguably, law), not political science.
A PhD in government pretty much guarantees that you'll be retiring after a thirty year career as a GS-15 or SES. A 150k salary plus benefits may not be high for some STEM fields, but it's definitely not something to look down on.
