3 days sound better imho .
Agree, ever other day would be fine. Outsource delivery to private contractors, and restrict USPS personnel to providing processing and deliver services to local post offices. Eliminate the barrier that currently prevents competition in letter mail and restructure all existing pensions into 401Ks.
A good goal ought to be to reduce the size of USPS by 50% in five years. Then take another good look at it.
Ditto. Deliver half the town on Mon/Wed/Fri and the other half on Tue/Thur/Sat.
