Steve's barking let's reduce unemployment by firing people

Now it doesn't take a genius to figure out that if you fire(lay off) people, the unemployment rate goes up, so why is the government threatening to lay off 160,000 postal workers, when it's the constitutional duty to have a post office, and if what the postal union is saying that the post office has to prepay well in the excess of what is needed for health benefits and retirement the deficit for the Post Office can easily be fixed.
