This debate is being framed as a change to benefit people down the road, but that's completely wrong. Increasing the retirement age and grandfathering it in is basically a wealth transfer from the young to the old.
Young people today are paying taxes to support a benefit level that they won't receive. We should lower the eligibility threshold/increase clawback instead.
