Someway and at some time, this nation will need to start paying down it's debt. Of course, one way to do that is to cut some government programs and cut out fraud, waste and abuse. Certainly!! But with the country's economy the way it is currently and the profound need to stimulate productivity and, thus, create retail demands for goods and services, the government cannot afford have anything near a spending freeze except in those areas most Conservatives would like alone - defense, homeland security, Veteran's Affairs and the military. You have people out there without homes, without jobs, barely able to buy food. And then there are the natural and man-made disasters that have adversely affected portions of this country, and there's no way you can cut service programs right now. It just makes not sense whatsoever to do that! So, on compassionate and humanitarian standing alone, you just don't do that now. Instead, you retain those programs (unemployment, welfare, WIC, etc.), increase taxes on the wealthiest individuals because they are the ONLY viable revenuse source who can afford to contribute more, and use those funds to pay down the national debt. Once the country's economy has returned to some form of normalcy, you re-evaluate the tax issue. At that point, lowering those taxes of the wealthy would be the right thing to do.
Now, if you don't think such a compromise could be trusted by the left, you simply state that you will not yeild on this issue unless and until a firm date (year) is stipulated within the proposed bill and the only way you'd accept those taxes not being reduced by that time is if the economy hasn't improved by then. To me, that's the best compromise Democrates can hope to achieve their goal whether Republicans win the mid-terms or not.
