Half the respondents of a new poll say taxing the richest Americans by at least 50 percent is a great idea, while more than a third consider Twitter a fad¹ that will likely fade.

Those are among the findings of a new "60 Minutes"-Vanity Fair Poll released Sunday.

Nearly half of the respondents chose Wal-Mart as the institution that best symbolizes² America today, leaving in the dust runners-up Google, Microsoft, the NFL, and the banking³ and securities firm Goldman Sachs.

Dining out was chosen most often by respondents as a luxury they hate sacrificing in these tough economic times. And 5 percent thought the best way to fight obesity⁴ among patrons of fast-food chains is to equip each restaurant with scales for them to weigh themselves.

A politician taking bribes⁵ is considered by far the greater sin (chosen by 37 percent of the respondents) when stacked against extramarital affairs (just 2 percent).

President Barack Obama has set a time table for a troop pullout in Iraq by 2011. But one-third of poll respondents predicted he won't be setting a time table for removing troops from Afghanistan. Meanwhile, 31 percent said he would time it to the beginning of the next presidential campaign, and 25 percent chose "in about a year."

Obama was edged out by George Clooney (24 percent to 26 percent) among respondents choosing "which man they would most like to trade places with for a week," followed by Tom Brady and Bruce Springsteen.

But among woman, First Lady Michelle Obama was the favorite, chosen by 26 percent, with Secretary of State Hillary Clinton picked by 16 percent, actress Angelina Jolie by 13 percent and singer Beyonce selected by 12 percent.

The poll is based on a random⁶ sample of 1,097 respondents nationwide. It was conducted by phone between Aug. 27 and 31 by CBS News.

根据一项新的民意调查，半数受访者认为把最富有的美国人至少一半的收入作为税收是一个不错的主意，超过三分之一的人认为微型博客Twitter这一风尚可能会在未来消亡。

这些调查结果均来自最近“新闻60分”与《名利场》杂志的民意调查，该调查结果于周日发布。

近半数受访者认为沃尔玛是现在最能代表美国的机构，人数远远超过谷歌、微软、美国橄榄球联盟以及银行和证券企业高盛公司。

绝大多数受访者认为在这种经济不景气的时候出去用餐是件奢侈的事，他们不愿意为此付出。5%的人认为，应对快餐连锁店食客肥胖问题最好的方式是在每家餐馆都配置体重秤供顾客使用。

巴拉克•奥巴马总统为2011年从伊拉克撤军设立了一个时间表。但是三分之一的被调查者预言他不会确定从阿富汗撤军的时间。另外，31%的被调查者认为奥巴马会把从阿富汗撤军的时机选在下届总统竞选开始的时候，而25%的被调查者认为会在“大约一年后”撤军。

当被调查者被问及“他们最想和哪个男人互换位置一周”时，奥巴马惜败乔治•克鲁尼（24%对26%），接下来就是汤姆•布兰迪和布鲁斯•斯普林斯汀。

如果和女人互换位置，第一夫人米歇尔•奥巴马是最受欢迎的，26%的被调查者选择了米歇尔，另外有16%的人选择了国务卿希拉里•克林顿，13%的人选择了女演员安吉丽娜•朱莉，12%的人选择了歌手碧昂丝。
