Many prisoners in Pennsylvania state prisons come from Philadelphia,
and many of them are held far away from there. The result is that
nobody
in their families can afford to visit them.
That makes them less likely to find a way to stay out of prison once
they are released.
Forbidding anyone who was ever in prison from visiting a prisoner has
the same effect of directing prisoners to become career criminals. It
is a reflection of the attitudes that make the US #1 in imprisonment.
The US asks, "What might that ex-con do if he visits a prisoner," and
not, "What might that prisoner do, after spending the prison term out
of contact with family?"
The policy of excluding former prisoners from all but menial work, and
from most educational opportunity, also pressures them into a life of
crime.
