根据下面资料，回答题 If the trade unionist Jimmy Hoffa were alive today, he would probably representcivil servants. When Hoffa's Teamsters were in their prime in 1960, only one in tenAmerican govemment workers belonged to a union; now 36% do. In 2009 thenumber of unionists in America's public sector passed that of their fellow members inthe private sector. In Britain, more than half of public-sector workers but only about15% of private-sector ones are unionized.
There are three reasons for the public-sector unions' thriving. First, they can shutthings down without suffering much in the way of consequences. Second, they aremostly bright and well-educated. A quarter of America's public-sector workers have auniversity degree. Third, they now dominate left-of-centre politics. Some of their tiesgo back a long way. Britain's Labor Party, as its name implies, has long beenassociated with trade unionism. Its current leader, Ed Miliband, owes his position tovotes from public-sector unions.
At the state level their influence can be even more fearsome. Mark Baldassare ofthe Public Policy Institute of California points out that much of the state's budget ispatrolled by unions. The teachers' unions keep an eye on schools, the CCPOA onprisons and a variety of labor groups on health care.
In many rich countries average wages in the state sector are higher than in theprivate one. But the real gains come in benefits and work practices. Politicians haverepeatedly "backloaded" public-sector pay deals, keeping the pay increases modestbut adding to holidays and especially pensions that are already generous.
Reform has been vigorously opposed, perhaps most notoriously in education,where charter schools, academies and merit pay all faced drawn-out battles. Eventhough there is plenty of evidence that the quality of the teachers is the mostimportant variable, teachers' unions have fought against getting rid of bad ones andpromoting good ones.
As the cost to everyone else has become clearer, politicians have begun to clampdown. In Wisconsin the unions have rallied thousands of supporters against ScottWalker, the hardline Republican governor. But many within the public sector sufferunder the current system, too.
John Donahue at Harvard's Kennedy School points out that the norms of culturein Western civil services suit those who want to stay put but is bad for high achievers.
The only American public-sector workers who earn well above $250,000 a year areuniversity sports coaches and the president of the United States. Bankers' fat paypackets have attracted much criticism, but a public-sector system that does not rewardhigh achievers may be a much bigger problem for America.
