The Philadelphia Fed provides the chart below detailing why businesses say they are not hiring. They are mostly concerned about low sales and wanting to keep costs down. This is what you would expect in a slow economy. Concerns about regulations are much lower. Concerns about health insurance costs are also much lower, especially as a most important factor. Given how variable they can be, we have seen increases of somewhere between 4% and 26% in premiums over the last ten years, this should be on the list in every survey. Of note is that this rates only a bit higher than concerns about labor costs being too high, in a market with excess labor.
