Nope. The exact opposite. Congress requires them to 100% fund their entire retirement fund. This is rarely achieved even in the private sector and unheard in government. The result is it massively increased their operating overhead. Stamp prices exploded.  To create their initial retirement fund nut, they were forced to sell off lots of property which friends of the deep state picked up super cheap, well below street value.  The USPO is the only government division which has this operating mandate. Coincidentally, it's one of the few government operations constitutionally mandated.
