Have you looked at the SBA? There's actually a fair amount of support there, including preferential treatment for bidding on set aside gov't contracts, including SBIR - Small Business Innovation Research contracts. Is it dollar and lobbying wise the same, no, but it is there.
I don't suppose I would want them to stop subsidizing certain deals in the private sector with corporate America. A lot of that seems to be smart business to me. But I certainly would like to see the government to place a higher value on small business innovation. Starting something from nothing is already hard enough.
