Pretty much right. Example, if you retire and have a lot of cash and a relatively small amount of tax-deferred savings (401k’s, Traditional IRAs, etc.), then you what you do is figure out how to get your ‘income’ to be in the Obamacare sweet-spot for the Silver Plan. If you hit that, then you pay virtually nothing for medical care.
The sweet-spot, I believe is about $32k for states that also have taken the Medicaid bait. So you add up your interest, capital gains, and any other income, then pull just enough out of your IRA, and if you nail it, you’ll hit that sweet spot where you’re considered ‘poor’, even if you have a million or so in cash laying around.
...and you are right, only the Silver Plans are subsidized in that way.
But you can’t get Obamacare once you’re 65. A lot of seniors will be passed because Medicare is going to cost them a lot more than Obamacare did!
