"From a tax policy perspective, the approaches of the two candidates are vastly different. Senator Obama emphasizes who gets what, and Senator McCain focuses on economic growth and broadly reshaping how the tax system affects household and business decisions. To put it differently, one focuses on redistribution and the other focuses on improving economic incentives. Also, focusing on who gets what is, by its very nature, more near-term, while promoting economic growth is more long-term.
One cannot get a good picture of what the candidates are trying to achieve by considering only the individual tax or the business tax provisions. One needs to apply a more holistic approach and consider the full set of proposals. Senator Obama provides tax relief directly to individuals, without major changes in how the tax system interacts with or affects individual and business decision making. Senator McCain provides broad tax relief and channels most of it to businesses, with the notion that the best way to help workers is to encourage investment and ensure that the U.S. remains competitive in the global marketplace. The policies present very different choices: redistribution versus economic growth, and short run versus long term." Quote from:

To me the business growth approach is more feasible, no bandaids on todays problems and if they need to it would be easier to adjust the numbers later as the economy changes.
