The current administration's budget director commented over the weekend that Social Security Disability is a "very wasteful program," that it is "the fastest growing" and that the disability component is not something most people think of when they think of Social Security. That SSD is characterized as "very" wasteful is usually the cue to make an argument that the program needs "reform" or, as he put, "fixed."
The trouble is always in what is meant by reform or fix. It is usually code for reducing the size of the program, which is why critics often try to make it seem that SSD is wasteful and many individuals obtained their benefits by fraud. Because, absent that line of thought, it is very difficult to see any circumstance where benefits to SSD recipients could be reasonably reduced.
