A key point to remember is that this was set by Congress and can be changed by Congress. I am expecting an "outcry" soon on people not being able to afford the copays and deductibles for their heath care. From a practical standpoint, a person with few or limited resources and a $6,750 deductible on their health care plan really doesn't have heath insurance. I saw an article recently that 50% of the US live paycheck to paycheck. Where are they going to come up with $6,750 or $13,500 to cover their OOP? The current law provides some relief in the form of subsidies but there is still a significant gap between what people can/will pay and their resources.
I'm not trying to make this into a politcal discussion but it is a wild card to consider. Laws change which makes it dangerous to predict the status quo too far into the future.
