I basically agree.
I think government worker unions, per se, are unconstitutional - maybe anticonstitutional would be a better word (because their "contracts" appear to bind future legislatures, and therefore violate the Peoples' right to govern themselves).
However
I was a letter carrier before I was a physician. There's nothing wrong with making that fundamentally blue collar job have a reward structure that's commensurate with the level of intelligence and responsibility involved.
And, since I live in the woods and rely on the mail, I'd look more to downgrading the direct competition with FedEx and UPS (which relies on a false model of USPS being a self-supporting business) and put the emphasis on first class, recognizing that it will always lose money (it always has), but the "losses" are a service to the taxpayers, who deserve SOMETHING useful from FedGov.
Excuse the ? but what type of ‘intelligence’ is required to match up numbers and road signs vs. the ‘responsibility’ of putting it in box XYZ?
Now-a-days, are they not sorted by a machine? One would think the only thing left is to load ‘em up, drive ‘em along the route and ensure their ‘delivery’.
No rocket science requiring a 6-figure income and same retirement bennies.
