It is hard to overstate the importance and impact of Social Security. For most people over retirement age, Social Security is their largest source of income; for 14 percent of those people, it is nearly their entire income. The average retired worker benefit is $1,779 a month, reflecting the 8.7 percent cost-of-living adjustment that took effect in January. As the nation remains mired in a period of high inflation, the need for Social Security is growing. Prices for basic necessities continue to rise. Many Americans have little or no savings. People are living longer, and employer-paid pensions are increasingly scarce. In addition, more seniors are single and lack family support.
