Rubbish! You've actually managed to annoy me with this statement. A grand unified theory is necessary for a true understanding of our world and the advances in this field come from government fuded sources.
Provided there is a grand unified and deep-pocketed tax payer base.
Sorry for that.
But really, I would imagine a researcher would be happy to do his/her work no matter who pays for it. Unifying the fund sources doesn't necessarily unify the work nor should it necessarily separate researchers into separate or partisan camps?
I don't have anything against NASA or patents that have been funded from government sources but I'm sure many good, useful inventions weren't funded this way.
