Krugman points out the major problem in the Republican tax cut legislation in 2017- not enough to help the middle class and adding 1 trillion dollars to the deficit. Krugman says even the Bush tax cuts had enough broad public approval because of help to the middle class. So what is the Republican message and rationale for taking this action? This is that the tax cuts will generate an economic boom . Yet the tax cuts in other countries including Britain, as Greg Ip pointed out in the Wall Street Journal recently, have shown that this does not lead to the boost in economic growth that is expected. Krugman agrees that this is unlikely to happen.

There is another rational explanation and this is Republican need for a legislative victory heading into next years midterm elections. In which case the decision for tax cuts was not really based on the deep sense and conviction after much debate that this will inevitably create a surge in economic  growth.
