I visited a zoo with my kids and a friend in their 30s last week. She grew up in a family living off benefits. I found out there that she had never been to a zoo before and do had never seen lions, giraffes, zebras or any exotic animals before.
My family were not well off, my dad was a physio and my mum a secretary, but day trips were an ordinary part of my childhood I completely took for granted.
Even if you take emotion out of it, keeping children stuck at home in a small world because of the choices/circumstances of their parents does not encourage them to act differently or break the cycle of poverty.
