I think the reasoning is that you likely won't get out of 1st at all.

  But that's not how economic mobility is generally measured. It's usually movement from bottom to top quintile. The measure is relative mobility within a society, not absolute mobility. But the WEF reference for the grandparent uses a "social mobility index" which includes such factors as: "Adolescent birth rate per 1,000 women", "Pupils per teacher in pre-primary education (%)", "Extent of staff training (1–7 best)", "Internet users (%)", "Meritocracy at work (1–7 best)", so it's clearly quite subjective when it comes to "social mobility".
