The adopted rule only affects the House, not the Senate, and the House can vote to waive the rule's requirements to allow reallocation, but they have unnecessarily blocked the simple and and sensible way to take care of the shortfall which has been used before - reallocation.
Over the last five decades, on a bipartisan basis, Congress has repeatedly addressed shortfalls in both of Social Security's two funds - the Old-Age and Survivors Insurance Trust fund and the Disability Insurance Trust Fund. A temporary shift of Social Security's incoming revenues to the Disability Insurance Trust Fund - called reallocation - will extend the Disability Insurance Trust Fund's solvency for almost two decades, without cutting coverage, eligibility, or benefits. This has been done without increasing taxpayer contributions and it has been done 11 times in the past, about equally in both directions - sometimes reallocating more to the the Disability Insurance Trust Fund and sometimes more the the OAS Trust Fund. Using reallocation, the solvency of the overall Social Security system stays the same, with the combined funds remaining fully solvent through 2033. See NOSSCR Social Security Forum, Volume 37, Number 1, January 2015.
President Obama's proposed SSA budget for fiscal year 2016 included a provision for a five-year reallocation, starting January 2016, to shore up the Disability Insurance Trust Fund. While it can be debated whether or not reallocation is a proper long-term solution, it is certainly a simple short-term solution that does not raise taxes and does not place disabled beneficiaries in jeopardy of losing their benefits.
