No, Taxes do not have to go up... Reckless entitlement spending has to stop. You don't stimulate the economy by raising Taxes... You stimulate the economy by easing the burden on the job creators.
47% of voters bought into that Romney bullshit.
But in fact, growth has always been higher when tax rates are higher. Fact.
Here's why: higher incomes far exceed the earner's spending needs. Thus the money sits and does nothing. So of some is taxed, and spent back into the economy, things get moving. It's called a "redistributive effect." Look into it, and not rightie-fear-mongering "Wealth Redistribution!!! Ahhh!!" and you'll begin to understand how modern economies function and grow.
