The point that BUS DRIVERS working for GOVERNMENT make better wages than BUS DRIVER working for PRIVATE sector. Not that bus drivers in general are rich people.
Ah. I think you've misread the comment in that case. The argument wasn't that the same job was typically better in private than government sector. It was that the types of jobs typically available in government (like the ones you mentioned) are viewed as less desirable in general, despite having good benefits, shorter hours, etc.
