Romney didn’t “cook up” the plan. Most of it was already part of his long-term economic plan.
With seniors wanting to work longer, taxing their social security benefits JUST because they decide to work is stupid. Why should two people get different amounts of Social Security simply because one is lounging by the pool and the other is still being a productive member of society (btw, we TAX the productive one who is paying income and social security taxes on their earnings, NOT the guy lounging by the pool).
