According to a national economist I interviewed, there is a balance between how much you can expand the public sector to create new jobs and how much tax increases this leads to and thus to fewer jobs in the private sector.
On the other hand, too many tax cuts and government employment subsidies for companies are an indirect way of creating public jobs. And national economic surveys have shown that a large part of the money the rich get in tax cuts is not invested in new jobs. I am convinced that we could in any case raise taxes to the 2006 level before the election, i.e. by 100 billion, and that this would create hundreds of thousands of new jobs even overall.
