I'm also a Medicare recipient and wish I weren't. I had good coverage with Blue Shield for a reasonable cost but was forced to take Medicare because Blue Shield drops you at 65, so it's Medicare or nothing. Although I'm healthy with no chronic medical conditions, it would be foolish not to take the Medicare coverage, such as it is. However, because I have little choice in the matter, I certainly don't consider myself a 'leech'. The Medicare coverage isn't free and I have no say in the premiums.
If Rush uses that term and means it, he is badly misinformed, which I doubt. Of course when you make 40 million or so every year like Rush does - and I don't begrudge it to him - it's going to be hard to relate to someone who has to take the government medical insurance or have nothing. That may be the crux of the problem if Limbaugh actually refers to Medicare recipients as 'leeches'.
In some states Blue Cross offered a Medicare Advantage Plan... may no longer be true. I am not saying Rush used the word 'leech', only that he has occasionally painted a picture of Medicare recipients receiving a free benefit [at the cost of others] - a term which I HAVE heard him use. It may be at the cost of others, but it is not 'free'. If anyone thinks the country would be better off without Medicare, I can see that.
