It's not that I have so much faith in the government. I can only make decisions based on my experience. And the private insurance companies suck (in my experience). Medicare was never difficult for me to deal with - they paid what they said they would pay, covered what they said they would cover.
And I'd be willing to try a government program if it was better than the $7000 yearly deductible that I have now and costs me about $250 a month. And I'm willing if the new plan covers my two children who are full time students and have no insurance.
