We are watching industries crumble, Wall Street firms disappear, unemployment spike, and unprecedented government intervention. And our designated opinion leaders want to know: Is Obama up this week? Is he down? And is his leadership style more like Bill Clinton's, or Abraham Lincoln's?

Money has transformed every watchdog, every independent authority. Medical doctors are increasingly gulled by the lobbying of pharmaceutical salesmen.

Liberal that I am, I support health-care reform on its merits alone. My liberal blood boils, for example, when I read that half of the personal bankruptcies in this country are brought on, in part, by medical expenses.

There are few things in politics more annoying than the Right's utter conviction that it owns the patent on the word 'freedom' that when its leaders stand up for the rights of banks to be unregulated or capital gains to be untaxed, that it is actually and obviously standing up for human liberty, the noblest cause of them all.

Our current way of regulating the financial system is dysfunctional. Oversight is dispersed among numerous confusing bodies that at times have seemed to be racing each other to the bottom. Setting up One Big Regulator would end that problem.

With paper printed books, you have certain freedoms. You can acquire the book anonymously by paying cash, which is the way I always buy books. I never use a credit card. I don't identify to any database when I buy books. Amazon takes away that freedom.

Take MediCal and Medicaid patients. All people have a right to quality care and they will teach you as much or more as your insurance and cash patients do.

It's important not to think about Bitcoin as a replacement for cash or gold or something that works alongside that; it's to think of it as programmable money. And we just cannot even imagine what that will be used for.
