Close, but more something like:

"Liberals seem to universally believe that the status you are born into will probably be the status you stay in your entire life."

The important distinction here is that competence isn't a factor and that the above statement is true in every measurable way.

It might be true that some people hold the belief but the belief is not true in "every measurable way". Otherwise you would never have stories of poor people becoming rich.
