According to this  new report from the Heritage Foundation,  the temporary tax credit President Obama proposed will not create sustainable  jobs needed for long-term recovery. They commend Congress and Obama  for trying to help workers who have lost their job, but suggest extending  the 2001 and 2003 tax credits instead. 
The credit proposed by President Obama  pays $5,000 for each new hire a business makes in 2010. Businesses would  also get refunds on their Social Security taxes if they increase wages  or expand hours for existing-workers. The credit would be capped at  $500,000 per business.
Congress tried a similar credit in the  1970s. It failed to create jobs, however, because much like today, policymakers  ignored the jobs the credit would destroy since it had to be funded  by government borrowing. Therefore, the current proposal must be evaluated  by its net job creation--a standard that requires looking at the jobs  created by the credit and the jobs lost because the government has to  finance the proposal.
On the positive side, according to the  Congressional Budget Office (CBO), the credit would create five to nine  years of full time employment for every million dollars of credits businesses  take. The White House estimates that the credit will reduce tax revenue  by $33 billion. Combining these two estimates shows that before offsetting  effects, the credit might create between 165,000 and 297,000 jobs in  2010. This works out to a cost of $111,000 to $200,000 per job created.
