> Several large studies of mobility in developed countries in recent years have found the US among the lowest in mobility. One study (“Do Poor Children Become Poor Adults?") found that of nine developed countries, the United States and United Kingdom had the lowest intergenerational vertical social mobility with about half of the advantages of having a parent with a high income passed on to the next generation.

The above quote from wikipedia article on mobility in the US [1] highligts an important point. The US as the land of opportunity is clearly a false image, since you have a lower chance of climbing out of poverty there than in a lot of other countries.
