http://www.cbsnews.com/news/for-third-time-in-40-years-no-social-security-increase-coming/According to the article, the other no colas were in 2010 and 2011, so that answers your question BF. But I think you already knew that and were making an observation statement.
Yep, the article even alludes to higher medical costs for seniors as well, as is usually the case.
Damn shame. They know that there are other factors affecting COLA to consider, other than oil/gas prices. And usually when there is a COLA, the medicare payments go up as much or more.
