While I generally oppose public money (TAX) being used loans backed loans are a different issue.
With BigCorp killing private research and investment (and payrolls) to enrich their mgmt and investors, Federal govt spending on research, science, loan guarantees, etc is the innovative engine driving the future. Fed's return on investments, interests on loans, is well positive. And the Federal "winner- picking" success rate is well above private rate. If the Feds "pick" Elio to be a "winner" with a loan or loan guarante, chances are very good Elio will be winner.
