Ultimately, I want corporations to be as profitable as possible, because that is good for our economy. Profitable companies buy and sell goods, hire individuals, the usual talking points. If we want to give more money to public education, increase income/capital gains tax (e.g. individuals)...not corporate tax.
Besides, you can make the case that only a small portion of the taxes Google pays actually improves the roads or public education. A large percentage will go towards things like defense research, healthcare, bridges in Alaska, any number of things that have no bearing on Google at all.
(I'm not a Google apologist, this would apply to any company.)
