> No, that's just false. It will pay for your future treatment as long as the insurance company is legally obliged to foot the bill.

You're assuming that the insurance will have money then. I'm pointing out what it takes to make that assumption true.

The relevant term is "counter-party risk", aka the "blood from a turnip" problem.

> the whole point of the insurance business is that a company is not guaranteed to make a profit on each individual customer.

While that's true, it's also true that the total payout plus expenses must be less than the total premiums plus any investment income. Savings and borrowing allows some time-shifting and smoothing but if payouts are too high relative to revenue, the company goes down, regardless of its obligations.

You believe that today's young will receive care when they're old that costs more than they'll pay then. Where is the extra money coming from? It can't be the extra money that they're being asked to pay now because that money is being spent now on today's old people. So, it can only be from tomorrow's young people.

You don't believe that future generations will pay your SS benefits. Why do you believe that they'll pay for your healthcare?
