IMI, Sorry for the confusion, however, it seems that the wage gap among the most educated people is increasing tremendously compared to less educated. However, the gap between high school graduates and college graduates is very high. If you are intelligent enough to understand research papers, do go over this paper. Here is a quote: "Like Mincer (1998) and Deschênes (2002), I find that the return to post-secondary education increased sharply while returns to lower levels of education remained relatively unchanged. Using quantile regressions, I show that the return to post-secondary education has increased even more in upper quantiles (like the 90th quantile). The return to post-secondary education has also increased in lower quantiles (like the 10th), but by a smaller amount than higher up in the distribution. But other than for this increase in the return to post-secondary education at various quantiles, the rest of the wage structure has remained remarkably stable over the last three decades. For instance, the experience-earnings profile, both at the mean and at various quantiles, has remained essentially unchanged since the early 1970s." visit it here: http://www.aeaweb.org/annual_mtg_papers/2006/0106_1015_1202.pdf This research was done by Thomas from the University of British Columbia
