I think it depends on what you consider Escapism I don't consider it a lack of bad things happening light can not be done well in a story without dark
however if you write something to teach people what you think they need to hear I do not consider that enjoyable if its meant to correct them
if you want to give people hope or make them happy then go a head but I don't think its right for our entertainment to try and correct us
because then its no longer entertainment but a lecture
