Here’s one reason:

WASHINGTON (Reuters) — Core consumer prices rose a moderate 0.2 percent in June for a third straight month, but the year-on-year rate hit a nearly four-year high, keeping financial markets on edge over a possible Federal Reserve interest-rate hike.

In the same report, the Commerce Department said Tuesday that personal income rose 0.6 percent in June, with nominal spending up 0.4 percent. The data, which was incorporated in a report released Friday on second-quarter economic growth, matched Wall Street expectations.

Here’s the other. Energy prices continue to rise which gives everyone an excuse to raise prices and also gives them an excuse to hold wages because of rising cost and decrease demand for goods. All the makings of problems. I am not negative because there are many products that will continue to sell well but until we get this gas thing figured out we are going to have problems.
