@allenJo - It’s not the middle class alone who need the tax rates cut. It’s the rich – in other words, the people who create jobs. Yes, those rich people; we are interested in creating jobs and reducing the public deficit aren’t we? Then we have to give businesses every incentive to hire.
So while I understand that it doesn’t sound politically expedient to say that we are cutting taxes for the rich, the harsh reality is that they are the job creators (for the most part) and we need to give them every incentive to create those jobs.
