No. The next one could be more, it could be less. There could be other fees. You have no idea, because there is no price transparency.
You obviously know this is true, or you wouldn't have used the words "likely to cost". You're just arguing to argue.
Go to the grocery store. There are no prices posted, you just take your cart to the register, and the cashier charges you $20, then sends you a bill in the mail for a random amount -- trust us, we'll figure it out! Oh, that can of tomatoes really was $50. Sorry. At least you know for next time, right? (Unless the price changes.)
Do you see the problem now? Would you really call this system price transparency?
Americans know intimately that doctors visits are going to hit them in the pocketbook. Far more than someone from a single-payer system does, where there's a good chance they will never receive a bill with a dollar amount on it.
Yet, we're the big outlier on medical costs. Knowing "this is gonna cost me, ooof" does not seem to have any impact on the costliness of the system.
