Mark Rank, professor of social welfare at Washington University, has an excellent piece in The New York Times on income inequality and mobility that further supports the video above:
But is it the case that the top 1 percent of the income distribution are the same people year in and year out? Or, for that matter, what about the top 5, 10 and 20 percent? To what extent do everyday Americans experience these levels of affluence, at least some of the time? …It turns out that 12 percent of the population will find themselves in the top 1 percent of the income distribution for at least one year. What’s more, 39 percent of Americans will spend a year in the top 5 percent of the income distribution, 56 percent will find themselves in the top 10 percent, and a whopping 73 percent will spend a year in the top 20 percent of the income distribution.
This demonstrates that
most American households go through a wide range of economic experiences, both positive and negative…Ultimately, this information casts serious doubt on the notion of a rigid class structure in the United States based upon income…Rather than talking about the 1 percent and the 99 percent as if they were forever fixed, it would make much more sense to talk about the fact that Americans are likely to be exposed to both prosperity and poverty during their lives, and to shape our policies accordingly. As such, we have much more in common with one another than we dare to realize.
