It's rather telling of the times we live in that a FB friend of mine turned 65 today, and the dominant message (after 'happy birthday') was some variation of "congratulations on getting Medicare".
Not too surprising for any time. The subsidy is nice even for those fully subject to IRMAA--which is alternatively known as "the Medicare subsidy reduction." https://secure.ssa.gov/poms.nsf/lnx/0601101001 (also observing that base Medicare B premiums equate to ~25% of the program's cost).
