European nations already have all the new and higher taxes American socialists want, and they have no military on par with the US, and they are still insolvent.
It's not the taxes.
To cut a deficit, there are only two options. Cut spending or increase revenue. If Congress could cut spending without wrecking the economy, then that would be a preferable solution. However, when Congress cannot cut spending the only alternative it to increase taxes.
The income tax has never been lower. Nearly half the country pays nothing due tax credits, deductions, and low rates. The sensible political solution would be a package of tax increases accompanied by spending cuts.
