最后是专业人才的系统性短缺。这是制约服务质量提升的最大瓶颈。从业者普遍呈现“高龄、低薪、低学历”特征，社会认同感低、职业上升通道窄，导致专业人才留不住，行业始终面临“有人干、没人会”的窘境。
The Arizona Wildcats have depth, a great coach and an overall talent pool to win the program's -- and the West Coast's -- first national title since 1997. That's why they've been picked by many fans to win it all. Here's a skill that might have been overlooked: an uncanny ability to get to the free throw line. College basketball fans tend to resent games that include a lot of foul calls; they'd rather see teams run up and down the court and keep things moving and exciting. But that kind of play doesn't always lead to victories. Arizona is one of the best teams in America at drawing fouls and getting to the free throw line, and it is effective. The Wildcats have averaged 26.3 free throw attempts this season. They've recorded 72 free throw attempts in two NCAA tournament games. Even if the shots stop falling, they can still put points on the board.

The U.S. does still import some crude oil, most of which is heavy oil from Canada handled at certain American refineries on the U.S. Gulf Coast. Factoring in those imports, net U.S. oil trade balance is a positive 2.8 million barrels per day, as contrasted with the mid-2000s, when the balance was a deficit of 12 million barrels per day.
