Leave Silicon Valley alone

Why can't this White House figure out that Silicon Valley is one of America's greatest assets?

On CNBC's Squawk Box earlier this week, Treasury Secretary Steven Mnuchin offered a cautious but nonetheless worrying answer when asked if Google was a monopoly: "As these technology companies have a greater and greater impact on the economy, I think that you have to look at the power they have. It's something I hope the Justice Department takes a serious look at."

Now, that's hardly the sort of language that energizes the radical "hipster antitrust" crowd of populist politicians and wonk-activists eager to dismantle America's largest technology companies.
