If you don’t cut out those departments, you are missing most of the graft. Do you really think the defense spending is paying for our “defense” or “people?” Those departments are where the huge spending is.
If you don’t meddle with interest, social ecurity, or defense— you could cut the rest to zero without a significant impact. The social programs need to be cut, but they, alone, are not going to do anything but tart a civil war.
I am not saying those are exempt from cuts. The intent of the post was to show priority 1 should be elimination of all un-needed and redundant services.
Once that is done, then do as you suggest cut and slice as needed.
