Rule #1: If you subsidize a thing, people will use more of it.
Rule #2: When the cost of the subsidy inevitably becomes prohibitive, ration it. So that, you know, the people you initially wanted to use the service, can’t use the service as often as you promised them.
Rule #3: If rationing doesn’t cut costs, then slash payments to the people providing the services.
This is where we’re headed with our health care, folks.
