I would like to state the above in a more fundamental way that gets to the heart of the problem - With what other product or service, besides healthcare and college, is the consumers’ costs covered by a third party and the consumer has NO CONTROL over the products and services he receives at a given price point? I say it this way because the consumer does have real incentive for the costs to be lower, as no one wants to pay a higher than required price, but the consumer in both these cases has no power to insist on lower costs.
Economically, the reason stores, such as Walmart, exist and services, such as Amazon, exist is the consumer is responsible for determining the final price paid for a good. The ability to not purchase is the control over the final price and is the built-in negotiation factor that allows for the consumer to shop around and get the best price. Thereby, leading the overall market, in the aggregate, to gravitate toward the lowest price.
However, in healthcare and in college costs, the insurance company determines price paid to the doctors/hospitals and the government pays colleges and gives students/parents loans, i.e., the consumer is totally disconnected from the payment process and thus has no control, read as no natural economic negotiation power, to demand a lower price.
This is a direct result of the horrendous decision decades ago to tie health insurance to one’s job and thus separate the consumer from the being ability to shop and get the best for the lowest price. Colleges suffer from the same structural issue because the student is separated from the loan money, as government gives the money directly to the colleges and thus the student has no control in negotiating prices.
This is economics 101 - that is, controlled third-party markets have no incentive to lower costs or to provide the best product for the lowest price because the consumer has no control over the final price paid, which leads the producer not having any repercussions for not responding to the consumer. Or put in the starkest terms, the consumer is not paying the producer and the producer knows he will always get paid regardless if consumer complains or does not like the service. Therefore, there is no incentive to care about what the consumer thinks, says, or does. The result - ever rising prices and poorer and poorer service. So predictable, and it happens every time it is tried.
