You must be a hit at parties . <| sep |> Economic mobility is a thing , and it can be measured . It ' s pretty well accepted that economic mobility is pretty shitty in the United States , it ' s just a fact . Doesn ' t it worry you that during the debate and once again , now , you reach for these wellaccepted facts ? I remember , for example , when you were talking with some guy he claimed that abuse of the welfare system is wellaccepted fact , you would not let him just take that position . You tried to grind actual numbers from him as hard as you could . As you should . But during this argument , you just gave that up . I honestly did not care that much about this specific issue I was more rustled by your view of the women in tech industry since that I what I actually know something about . Even the Wikipedia article you linked me . Did you bother to read the actual sources behind your ' facts '? 5794 It ' s undeniable that somebody born middle class will tend to be middle class . The source in your link says something completely different . Some quotes Ninetythree percent of Americanswhose parents were in the bottomfifth of the income ladder and 88 percent of those whose parents werein the middle quintile exceed theirparents ' family income as adults . 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 . And even the edge quintiles are not as dramatic as the ' By contrast ' would suggest . If you actually look at the numbers , majority of people are likely to move between the quintilies . Does that sound like well accepted fact with ' sure , exceptions happen '?~ m e d i a l e g a c y u p l o a d e d f i l e s w w w p e w t r u s t s o r g r e p o r t s e c o n o m i c m o b i l i t ypursuingamericandreampdf . pdf
