The whole appropriations process is confusing. You may wonder whether it matters. Let me put it in terms that people can understand. Social Security's plan to start working down its hearing backlog by hiring more ALJs probably went up in smoke. There's no money to increase the number of ALJs without cutting something else. The agency's plan to reduce the hearing backlog with senior attorney and re-recon decisions probably went up in smoke also. They needed to hire more people and use more overtime for this. The money's not there. Improving service at the field offices in any significant way? No money for that. Improving computer systems? No money for that.
By contrast, the National Institutes of Health got a near 7% increase in its budget. I'm sure that's money well spent but the money would have been well spent at Social Security also.
