It would be nice if politicians and regulators left us alone. But they don't. They always want to do more. Recently, there have been shortages of some medicines. Cancer patients can't get drugs they need. Why not?

One reason is that a big drugmaker shut down for a year in part to meet Food and Drug Administration rules. The FDA makes it so expensive and difficult to sell drugs that there isn't an eager pack of companies rushing to the fill the gap. The free market would provide that, but government intervention, such as low Medicare reimbursement, strangles it. So people suffer.

Does the FDA say it's sorry for its part and back off? Of course not. Regulators almost never do that. In fact, the FDA wants more power.

It wants to regulate how your doctor uses his smartphone. I'm not kidding! The FDA wants the power to approve mobile medical apps that let doctors monitor patients' vital signs over their phones. As one doctor put it, "Even though I'm away from the hospital, I can still look at ... real-time wave form data just as if I were at the patient's bedside."
