This guy takes a look at the question not just from one point of time compared to another or in the sense of a gap, but addresses income mobility as well as immigration and young workers and makes some interesting points.
In his mid-April speech on the budget deficit, President Obama echoed conventional wisdom when he cited the rich are getting richer and the poor are getting poorer as a reason to raise taxes on the wealthy in order to reduce the national debt.
Research, published at The Journal of Policy Analysis and Management, from Cornell economist Richard Burkhauser, Joint Committee on Taxation economist Jeff Larrimore, and Indiana University economist Kosali Simon, however, suggests that the president’s piece of conventional wisdom isn’t entirely accurate. According to the findings, while the rich have indeed been getting richer, for the last 30 years so too have the poor and middle class.
Burkhauser told The Daily Caller that Obama’s suggestion that the poor are getting poorer understates the amount of income to which Americans actually have access. The president does not take into account, Burkhauser explained, tax unit shifts, government transfers, and other sources of income such as health care benefits.
“The bottom line is [conventional wisdom] asks what’s been happening to private personal income over time and they are right if you look at that for tax units, things do not look very good for the middle class,” he said. “But if you take other things into account, the reason the country has not gotten in a civil war is because things are not that bad. In fact everybody has done better.
