The Kauffman Foundation recently released their State of Entrepreneurship report and new business creation is at an 30 year low. Why?

None of the above.
Simply put, even the courageous risk takers are scared of the current business environment.
1. A vocal set of people in power constantly talking about higher tax rates that creates a lower reward to risk ratio.
2. An unstable regulatory platform that continually adds expense to domestic business's with dubious overall benefit to the nation.
3. Uncertain wage and benefit costs that negatively effect risk decisions.
