We could easily support government grants to Open Source developers and companies without needing to increase taxes. It should already be part of the NSF grant process that funds a large number of universities, who's research is also given away for public use (most of the time). Sure, you'd have to fill out lots of forms and be at the mercy of the bureaucratic grant submission system, but that process already has mechanisms for managing IP and leaving ownership with the grantee. Despite its frustrations, it is already a much healthier way of developing IP compared to the VC-supported route.
