President Barack Obama has proposed adopting what is known as a “chained” Consumer Price Index, or CPI, as part of his plan to reduce the nation’s deficit and raise revenue through an income tax hike on wealthy Americans.In general, people who would be negatively affected by the use of the chained-CPI would be retirees and other beneficiaries who receive most of their income from Social Security and who aren’t in a position to switch to other goods and services when prices rise.
