Edit: Just to be clear, obviously techniques and procedures get ever more sophisticated. The question is more specifically whether the average person is seeing an improvement in care that is proportional to the increase in costs. E.g., if office appointment costs have doubled for someone over the past ten years, have they seen a double or greater increase in effectiveness of care? Or is it just more expensive.
If there are components of compensation which are cheaper to provide now than 30 years ago, receiving the same thing in that case is counted as lower total compensation.
Or to put it another way, if employer share of health benefits stayed exactly the same and employee share took all the hit, and instead, your paycheck increased — leaving total compensation at exactly the same dollar amount — would you consider that as better compensation? Because under that scenario you would be worse off after taxes.
The problem is on the medical services side. We're get the same or slightly better medical services for 200-300% the cost.
Some would say receiving the same thing is not an increase, even if the sticker price is higher.
