I propose that people who are eligible for Social Security retirement who also have IRA's and or 401k's be allowed to take funds equivalent to twice what they would have earned in Social Security payments for a calendar year from their IRA/401k. As I'm not an economist I don't know what the most appropriate multiplier might be.
Once they are ready to start taking Social Security they can take it at the rate they would have taken it had they not withdrawn from their IRA/401k's.
Thus Social Security stays solvent a bit longer and those who are lucky enough to have saved can reap some reward in lower taxes in the out years.
