万宝盛华集团(ManpowerGroup) 2012年的调查报告显示：美国专业技工短缺。美国要填补熟练技工的空缺非常困难。劳工统计局的报告说，三分之一以上的熟练技工都在50岁以上。事实上，每三个退休者中只有一个技术人员接受培训以开展工作。这些趋势可能意味着美国经济复苏会遇到麻烦。管道工，焊工，屋顶工，泥瓦工，汽车修理工短缺，这也说明他们的辛勤工作未能收到尊重和肯定。（E)

ManpowerGroup: America Needs Skilled Tradesmen
(Sept. 17, 2012HUNTERSVILLE, N.C. /PRNewswire/) -- America has a shortage of professional tradesmen. According to ManpowerGroup's 2012 report, our nation's number one category of the hardest jobs to fill is that of skilled tradesmen. The Bureau of Labor Statistics has reported that more than one third of skilled tradesmen are over the age of 50. In fact, for every three tradesmen who retire, there's only one skilled person trained to perform the work. These trends could mean trouble for a rebounding America. At the heart of this shortfall of plumbers, welders, roofers, masons, auto mechanics and other skilled workers is a culture that fails to honor the hard work that these men and women do every day.
