This is somewhat misleading: It's not exempt statewide for all employees in those locales, only for certain employees like teachers and firefighters who are paying into alternate pension systems. The headline number is 6MM people aren't paying in, but the combined population of those states is almost 112MM and the total population is 319MM. It's a substantial number, I suppose, but not like 30% of the workforce.
