The argument the writer is making is that to make the current FERS retirement payments the government incurs debt elsewhere, so that debt should be attributed to the FERS retirement costs.
I earlier pointed out (every time this approach is used in fact) that if the US government got rid of every employee and quit paying federal retirements, the US government would still incur new debt!
The federal employee part of the total cost equation is MINOR. You will get your big bucks out of all the other nonsense the federales do ~ renting range land to cattle ranchers, purchasing property for national parks, regulating drugs, grants to universities, grants to hospitals, grants to grant granting organizations, and so forth.
Seems to me that it should be pretty simple to cut federal costs ~ eliminate every expenditure except those related directly to national defense, and sell the postal service.
The military, Iraq and Afghanistan is just a weird jobs program now. Note: I am not disparaging the troops. Sadly - they are used and abused by the elites. The elites who hold power because they control TV and because idiots watch TV.
