Yes, we need to grow the GDP. I have seen no evidence that anything the government is doing does that.
Plugging loopholes and bringing American industry back to America might help.
Government spending has doubled in 11 years, too. In addition to raising taxes, we have to cut back the out of control growth of government.
We live in a global economy, we have to stop pretending like we don't.
That said, if you see no evidence that anything the government does grows GDP, why are you so certain taxes must be raised?
