The Wall Street Journal (WSJ) spoke to Sheldon H. Danziger about the complexity of ranking American's income mobility. According to the article's author, Americans tend to shift income categories rather frequently, but are doing so less often than counterparts in Canada and Western Europe. "Yes, the U.S. has a lot of mobility," Danziger explained to the WSJ. "But we also have a lot of inequality, and particularly a lot of stickiness at the top and at the bottom."
The article goes on to explain there are multiple measures of mobility, including economic and relative, and that the factors of mobility are complex. "Everybody is right in what they say because it's a complex issue," Danziger added.
