what's worse is that when the kids need therapy - and as you say, the majority of them will for the way that Sue and Nowull have totally messed up their childhoods and exploited their privacy on a daily basis - they will know damn well that the money they earned as kids could have contributed to paying for private therapy and actually benefit them - not that NHS therapy isn't equally as effective, just thinking of the huge waiting lists and delays - yet instead, their parents spent it all on expensive holidays and fancy meals out for themselves and ugly designer clothes for Sue etc etc. same with how the money they earnt could have been put away and saved for the future, so the kids could use it as a deposit for a house or whatever, not spent frivolously by Sue.
it's very clear that Chris could desperately benefit from therapy - and whilst he is now old enough that it's his responsibility to seek the help he needs, that isn't to say that his messed up childhood and the horrendous circumstances surrounding his conception etc could have been addressed and worked through in therapy as a kid or teenager, and may not have had such a negative impact on his adult life. and with Chris as an example if how Scatty and Nowull have failed their kids as parents, it only indicates that the majority of the younger kids will need therapy due to being ignored and brought up by their elder siblings, only paid any attention from Sue when it benefits her for content and having toys and tat thrown at them in replacement for love and affection - the bulk of which indicates that she knows absolutely nothing about her children as individuals.
