The poor peoples' colony
Why did the owners of Leisureland allow the poor peoples' colony to exist outside the wall? There is no way it could be there without them knowing it, but the hole in the wall was surely a major risk to Leisureland because all sorts of critters could get through it and cause havoc in the dome. If the owners did know about it - maybe they even built it themselves so that cheap labour would have somewhere to live - why wasn't there a border control at the hole to stop insects, rats etc getting down it?
I realise the 'Hollywood Agenda' is obliged to make some sort of oblique references to illegal immigration, the Mexican wall etc but it just doesn't make sense in this context.
