The reason senior citizens are concerned about changes in SS is because the government has been lying to them for longer than younger people. If any politician would own up and tell the truth, that the "contribution" is really just a general fund tax, and that the government would have to replace the income if the system was "privitized" (2004- SS contributions of $522 billion of the 2.92 trillion budget or about 18%)and growing at an increased % rate at about 4% annually, due to be equal in 2018 leaving $26 trillion in unfunded liabilities, then and only then, will the people take a serious look at the "system", and "trust" that politician (oxy-moron) to do what is right for Americans rather than what is "self-preservationist" for himself.
The seniors should also be honest with themselves and admit they are on welfare. SS is nothing but a welfare system by a different name.
