I didn't say any particular thing was invented in the USA.

Almost all of the list was not invented in the US. This country didn't invent highways or automobiles for instance. That was just a quick, off the top of my head, list of good things about the US. I think you have made the case that penicillin was discovered by Flemming. But is is a fact that it was first made into medicine by a huge concerted the US government (Yes Tea Partiers, the Government) You might also hve noted that the light bulb was not invented by Edison, simply brought to market by his perseverance and effort. If you choose to dispute any one or two items. I don't think it detracts from the list.

Are we done with this now?
