With respect to health care, you may be able to make such educated decisions, almost no one else can. There isn't enough signal, and almost no one has the ability to distinguish signal from noise, and correctly interpret it.
What happens is that when given the opportunity, business will pollute the market with proxy signals (like brand trust, or fear based selling) that people instinctively respond to.
These proxy signals will be subject to manipulation by well-capitalized actors and will not in general reflect outcomes or value. They will interfere with the fundamental signal, making it even harder to detect and interpret.
Therefore the market will not work, in the sense of delivering the best outcomes for costs.
(Note that I am strictly speaking of healthcare, where even experts are often unsure of causal relationships and the relative value of various therapies. In general I think markets are a wonderful thing. Here is an experiment to try... take a mild condition treatable by OTC medication, such as the symptoms of colds, allergies, etc, and see how long it takes you to identify, characterize and factor the available therapies, and then map this to available products. Evaluate interactions, cautions, effectiveness, risk, convenience, costs, etc. Now ask yourself, where did you get your information? Who did you have to trust? Why did you trust them? Is the basis for your trust and understanding available to the average person?
I've done the experiment. My conclusion is that healthcare large and small is not like other goods.)
