The main issue with raising Medicare eligibility is not financial
Hey, Jon Walker! You write: "Medicare is in serious danger and so is your wallet."
True, but, "Medicare is in serious danger and so is your life."
At least if, like so many, you've been going naked because you don't have health insurance. When you decided to take the risk, maybe you did so because with your healthy life-style that made sense -- no High Fructose corn syrup from Big Food, no stressors from Big Media, no rent to Big Money, and as little rent as possible generally -- or maybe you did so because you had to choose between fuel or food and paying for junk insurance that probably won't cover you anyhow. And although Obamacare will force you to buy junk insurance, it's still going to be junk, because that's how health insurance companies profit.
For whatever reason, you took the risk knowing that Medicare would kick in at 65. Except Versailles -- and this would include the Democrats and the "progressives" who enable them -- decided to change the rules, and shift more risk onto you, so their rentier owners can make more money.
Do the math. The average life expectancy in America is ~79. (Countries with single payer plans do better, of course). Assume you're 60 because that's a round number. 79 - 65 = 14 . 79 - 67 = 12. 14 /12 = 117%. [UPDATE But jm corrects my math. --lambert]
So what Versailles did, if you don't have health insurance, is increase, by 17%, the time you still won't be covered. This will cause a statistically predictable number of excess deaths, for those made their decisions before Versailles trapped them by changing the rules. In fact, we have Medicare precisely to prevent those deaths.
Since the logic is so simple and clear, I can only assume that the Powers That Be, including all legacy parties and President Hopey Change, understand it, and that therefore they want a certain percentage of the population to die, who would not otherwise do so.
We don't have to fall in with their plans, of course. But that's how they think, and that's what they want.
