Right, I have seen that research before, and I don't think you should be getting down-votes either.

The relevance of social mobility in the discussion was because the GP assumes the correlation that the problems related to inequality/poverty is the result of a third factor that is cause of the other to: personal choices.

My position is that if this is the case, we should be observing strong social mobility in both ways. Surely there are a number of "deserving poor" that started life in a disadvantaged situation but are able to lift themselves out of that by intelligent choices and hard work, as well as there are privileged folks who make enough ill choices and land themselves in trouble.

IF this is not the case, we should adjust the level of agency that people are capable. To what degree is it personal choice able to influence the well being we enjoy in life.
