The phrase "at which benefit" is not correct and does not convey a clear meaning in written English.
It may be intended to refer to a specific advantage or gain, but the phrasing is awkward and unclear.
Example: "We need to evaluate the project at which benefit we can maximize our resources."
Alternatives: "for which advantage" or "in terms of benefit".
Mr. Moynihan has long advocated raising the age at which retirees can claim benefits and trimming back the rate at which benefits are adjusted for inflation.

Accelerating that transition, or raising the ages at which benefits can be claimed, would eliminate the strain that our increasing longevity is putting on the system.

Taxes further erode benefit payments because the levels at which benefits become taxable — generally, $25,000 for individuals and $32,000 for couples — have never been adjusted for wage growth or inflation.
Veterans and their families often praise the dedication of health-care providers, but at the same time express utter frustration over incomprehensible thickets of rules and the glacial pace at which benefits and appeals are decided.

The president has proposed slowing the rate at which benefits increase over time, a change that would ultimately hit the oldest of the old, often single women, many of whom have probably exhausted any other savings.
Nicole Maestas, an economist at the Rand Corporation, has examined Social Security data with fellow economist Kathleen J. Mullen, and concluded that in the absence of benefits, about 18 percent of recipients could work and earn at least $12,000 a year, the threshold at which benefits are suspended.
Further savings would come from slowing the rate at which benefits to upper-income earners grow and raising the maximum salary subject to the payroll tax.Rising health-care costs are more difficult to deal with, largely because of rising demand for services and an ageing population.
