Until recently, ML consistently encouraged all young people considering uni to not worry about finance on the grounds that if they didn't get a highly paid job then they would never have to pay back the debt/tax (he prefers to call it a tax). While true, that was an unaffordable reality for the taxpayer. Inevitably, the system was changed in 2023 and graduates of the new scheme are much more likely to pay back their debt/tax. Cue lots of discussion here on Mnet and elsewhere about whether the high cost of a degree is worth it and, now, ML is starting to weave this narrative into his journalism. Given his influence (i.e. most UK students and parents are familiar with his narratives on student finance), it'll be interesting to see what impact it has and how it evolves over coming years. For now, he's collecting stories, and treading carefully as it's obviously an emotive subject.
