QUESTION
What is likely cost or tradeoff of each course of action?
ANSWER
Trimming benefits, revising eligibility rules, and requiring the affluent elderly to pay more of their own health care costs will mean that retirees have to adjust to reduced benefits; they will have to work a year or two longer before qualifying for retirement benefits; and some will have to pay a larger portion of their own medical costs.
