while I might quibble about the "mostly" in that "mostly untrue" assessment of the email, I found the link to be well worth reading. Obviously the email was partisan, but I well remember many of these changes in Social Security over the years, and can vouch for them being heavily supported by most politicians of both parties in general. "Social Security" has long been the political Holy Cow people have relied on instead of saving on their own account and providing for their own retirement security, all the while the value of people's retirement funds have been decreased by heavy inflation in costs of goods and services essential to life, caused by deficit spending. Putting money in the bank just makes no sense when bank interest is less than the currency devaluation year after year.
I think the Republicans deserve their share of responsibility for going along with this nonsense in the political rhetoric as they do.
Federal "Social Security" is a bad program, a cancer in our society that should be cut out, with a return to limited government power over our lives.
