Hehe , ahh , fucking cod <| sep |> I ' m wearing a Maryland flag shirt right now . I think the only state that likes their flag more is Texas . <| sep |> What about Mafia III ? I could do both of those for yours if you ' re interested <| sep |> I don ' t know which one of us are reading the numbers wrong . It sounds like your idea of economic mobility is that majority of people improve their situation . Even this last quote clearly states that majority of people move between the quintiles . I ' m sorry , can you show me in here where middle class experiences perfect mobility ? Scroll two pages down . By contrast , thoseraised in the middle income quintile come closer to experiencing mathematically perfectmobility , in which they are equally likely to end up in each quintile of the distribution . This is what you ' re looking for . Middle class quintile movement chances 17 % top 24 % fourth 26 % stay in the middle this is the undeniable fact you are claiming 17 % second 15 % bottomWhen you say ' tend to ', you are trying to make it sound like the majority of people will not move to different quintile . But the reality is that ABSOLUTE 74 % majority of people tend NOT to stay in the same quintile . Do you see the difference between chances that out of those 5 quintiles , if you were to pick one , they have slightly higher chance to stay in the same one ? But when comparing them against the odds of moving to no particular , but still other quintile , you get a completely different picture ? edit To add to my answer middle class comes close to perfect economic mobility because the chances of moving to some other quintile are fairly equally distributed .
