It's common conversation to point to the shrinking ability of Americans to change income quintiles, compared to their parents. I've long hated this conversation because no one ever presents the actual quintiles. This is an important piece of the conversation because it provides some context for the rising difficulty in changing brackets. I've finally found a decent breakdown of how the quintiles have changed over the years.
In 2010 dollars:
The 1979 average difference between quintiles = $29,235
The 2010 average difference between quintiles = $53,750
Just on that alone, it's obvious that is should be harder to change quintiles now than before. Our quintiles have almost doubled in scale. That means the guy in the 3rd quintile has to essentially make 2x more money than his parents to change quintiles. He can actually make an entire 1979 quintiles' worth more money than his parents and never change 2010 quintiles. Even if we exclude the highest quintile, we find that the average difference between quintiles is still 33% larger in 2010 than in 1979. That should help us understand that the failure to change quintiles doesn't mean that today's generation isn't making significantly more money that they're parents. We are better off in terms of actual income, even if not in terms of changing quintiles (which doesn't really mean anything of value if the quintiles have changed as much as they have).
Furthermore:
The lowest quintile is now 40% larger than it used to be. (0-17,200) vs. (0-24,100).
The 2010 quintiles have cutoffs that are 40%, 26%, 25%, 35% and 78% higher than their 1979 counterparts respectively.
In total it shows that the average American is making much more money than previously and that the inability to change quintiles is reflective of the reality that more people are making higher salaries, requiring significantly larger jumps in income to change brackets. Characterizing the inability of modern Americans to change brackets as problematic without acknowledging the change in the scope of those brackets is a very disingenuous approach that leads individuals to feel that they've lost something that they haven't.
This isn't to challenge the reality that the top brackets have taken home a larger share of both pre- and post- tax income (especially the top 1%). Only that income quintile conversations don't make a lot of sense. So please don't take this as an attempt to ignore that stark reality.
