Am I wrong that Obama's chained CPI proposal exempts the bottom 20% of seniors?

99. It understates the inflationary impact of rising health care costs for seniors.

This "discussion" is about the impact of inflation on various demographic groups based on the percentage of their incomes that get spend on different categorizes. You realize of course that there are very few "average" Americans, kind of like it is difficult to find a family with 2.2 children? An "average" person might spend 20% of their income on housing. A poor person is lucky if they only have to spend 40% of their income on housing. When housing costs go up it hits the poor harder than the middle class. When medical costs go up it hits the elderly harder than the middle aged. Fortunately, since all of us hope to be elderly some day, FDR and Democrats after him built in safeguards to buffer that impact for Seniors - programs like Social Security and Medicare, the benefits for which are annually adjusted upwards to compensate for inflation. If a Senior has her medical expenses rise by 10%, that aspect of inflation is eating up her income faster than it does for an average American. Even under the current measure used to calculate overall inflation rates, Seniors are losing ground. Their bills are going up faster than the Cost of Living increases in their benefits currently compensate for. Under the Chained CPI formula, they will fall behind even faster.

IT IS EXACTLY THESE TYPE OF DETAILS THAT EXPLAIN HOW THE GOVERNMENT "SAVES" MONEY ON SOCIAL SECURITY PAYMENTS BY SHIFTING TO THE CHAINED CPI.
