I don't think a lot of people understand that for a low income senior, like those with Social Security as their only source of income, a $30 per month increase in a premium can be the thing that pushes them from being able to manage and not. My sister, who didn't work much outside the home (she raised several children and was a homemaker for most of her life) and gets most of her social security from her deceased husband's benefits, gets less than about $1000 per month. A little more than half that goes to rent --and it's a miracle she was able to find a place that is not a dump for that amount. It sure doesn't leave her much for food and everything else. Fortunately, she and I are both on a good medicare advantage plan that includes a good drug plan and doesn't cost anything beyond our regular $104 or whatever it is Medicare premium. She has several medical issues and would be in deep trouble were it not for that advantage plan.
Jujube, I'd be afraid to drop that drug plan, too. At our stage in life, you just never know what's around the corner.
