The Post Office is a legal monopoly and has already been in bed with Fed-ex.. illegally I might add. They have used Fed-ex services..and have their boxes on government land. Already they have been acting illegally

it could be there corrupt

The disgrace is that it isn't just the PO they want to sell but public lands, highways, bridges. These would in effect become taxes again on the people least able to pay them.The wealthy can fly their planes and helicopters and get a tax deduction for them while everyone else would have to pay for what they should own already.
