> I just read where Tesla (an HN favorite) gets tax credits of something like $35k (tradeable to other mfgs) for each car they sell. Forgetting whether that number is right or not (maybe it's less/more who knows) does that mean that they should somehow in ratio reduce the price of their car? Of course not (unless they want to). Even though one could make an argument that it isn't fair that they don't. To me all this is nonsense. But fully understandable if someone has never operated a working business.

To be fair, how you run your business depends greatly on this. Other companies would distribute the profit from this tax credit to shareholders or executives; Tesla is using it to continue with R&D and to fund expansion.
