Well, LSE doesn't rank higher than Duke or Penn on either times or QS historically. ICL ranks higher than Columbia, but that doesn't make it a better school. The US schools are far more selective, and produce more research. Duke for instance receives $ 1 billion every year just to conduct research. Do you believe ICL or UCL can hold a candle to those numbers? Also, the historical difference between Duke and UCL is a mere 3 spots. Do you think that number compensates for the disparity in research and student faculty interaction? To put the rankings more in perspective, Duke went from being ranked 52nd in the world in 2004 to 11th in the world in 2005. How much emphasis can you really place on rankings that are so variable? Do you really think the University of Edinburgh is 50 spots better than Dartmouth?? The fact remains that these rankings try to accommodate more European and Asian schools in an effort to come across as egalitarian. Whether we like it or not, we cannot compete with the Americans in the education market. To illustrate the anti US bias, take a look at the financial times MBA rankings. Previously unranked IIM A (india) is ranked higher than Chicago's Booth. This is in spite of the fact that an IIM A grad earns $25,000 dollars on average, and a Booth grad earns $170,000 on average. See what I mean?
