As Americans stretched to pay the tax man this week, California Assemblyman Charles Calderon was working on the sly to institute a new digital tax. Such a move is not only short-sighted, but also could seriously harm the state's competitiveness. It's no secret that the digital economy is a key driver of California's economic growth, so it is shocking that some political leaders seek to increase the regulatory and tax burden on the tech sector. In the short term, new taxes might help battle California's massive billion deficit. In the long term, however, the results would be disastrous.
