Are you a Fox News Watcher?
If you don't like the rate hikes from Kaiser Permanente, a private insurance company, find another plan from another private insurance company. Use your State Exchange if your State has one or, if you are in a State governed by idiots, use the Healthcare.gov site.
Your insurance through Kaiser doesn't affect your Medicare coverage or your Social Security.
And I call bullshit on your claim that you are paying a 10% Medicare Tax on your income, the tax for Medicare in 2013 would 3.8% plus an additional .9% IF your income as a couple exceeded $250,000.00 a year.
Stop watching Fox News.
Go get the insurance you want for less money, the ACA gives you the ability to change your PRIVATE insurance company without penalty or loss of coverage.
I've worked with several Fox viewers who were absolutely sure the ACA was having a bad effect on them. (One of them had had their Catastrophic Policy cancelled~it would have only covered her in the most extreme circumstances ~but she thought it was the only insurance she could afford because of something she had heard on FOXNEWS. GAH) We took about an hour on two separate days to find her better coverage for ......wait for it....less than half of what she had been paying.
