Herein you have all sorts of nuggets: production comes first, consumption comes second; all the important things happen on the margin; free markets can triumph over all sorts of adversity; and price discovery is essential for prosperity.
The late Arthur Seldon offered a darn good, and nicely concise, list of the important foundational tenets of economics:
Production takes place for consumption (derived from the Scot Adam Smith), not the other way round. Value is measured not as an average but at the margin (the Englishman W. S. Jevons, the Frenchman Leon Walras, and the Austrian Carl Menger). The cost of producing a commodity or service is not the labour required (the German Karl Marx) but the commodity or service thereby lost (the Austrian Friedrich von Wieser). The instinct of man is to “truck and barter” in markets (Adam Smith). He will find ways round, under, over or through restrictions created by government (the Austrian Eugen von Bohm-Bawerk). There is no such thing as absolute demand (for education, medicine or anything else) or supply (of labour or anything else) because both vary with price (the Englishmen Alfred Marshall, Lionel Robbins and many before and since). Not least, without the signalling device of price, man cannot spontaneously and voluntarily co-operate for prosperous co-existence (the Austrian Ludwig von Mises and the Austrian-born but voluntarily-British Friedrich Hayek).

This last dictum is especially important to the healthcare debate, since we most certainly do not have a price discovery mechanism in the healthcare market today. Since the consumers of healthcare are for the most part not the ones who pay the bill, there is no price discovery, there is no transparency, and there is no way for competition to work effectively to reduce prices and improve services. We must get rid of the third party payer problem if we want to have any chance of improving the healthcare industry. That can be accomplished very easily by changing the tax code: for example, let everyone deduct the cost of healthcare insurance. Why is this so hard for our politicians to understand?
