Tax cuts...are they worth it?

President Obama's deal with the Republicans include extending the Bush era tax cuts as well as unemployment benefits. The only socialist in the congress Bernie Sanders is threatening a filibuster as he objects to allow tax cuts for the most wealthy 1% of the nation. For Sanders he sees the tax cuts as reckless government spending. Looking at the Bush tax cuts subjectively we know that will see there effects very quickly but they will only be effective as the MPC of people that receive the rebate. In economic times like this people are less likely to spend they did in the 2004, 2005 and 2006 when they first received these checks. Therefore the boost to the economy will have less impact, so Sen. Sanders does have point in this respect. What do you think?
