What's Holding Back the Hiring

According to the congressional Joint Committee on Taxation, ObamaCare will hike taxes an estimated $15.2 billion,

Moreover, employer mandates, taxes and penalties will reduce funds available for private-sector hiring. 

Restoring American Financial Stability Act of 2010:

Decisions about investment and hiring will be delayed for quite a while — with millions of Americans out of work — until all the regulations are issued, and it becomes apparent what their impact will be. 

For example, the law will probably increase the cost of buying derivatives to hedge the risks of exchanging a foreign currency for U.S. dollars, as when a product is made in the U.S., sold overseas and paid for in a foreign currency (like euros or yen). If the hedging cost is too high, more companies are likely to lay off American workers and transfer manufacturing offshore where products will be sold, so costs and revenues will be in the same currency. 

...higher spending must be paid for with higher taxes that will reduce the after-tax return on investment. Consequently, rather than making capital available now, many investors remain on the sidelines, and many businesses are sitting on cash, waiting to see how high the taxes are going to be.
