I think you’ll find that descent down the slippery slope started a long long time before DEI. The roots of that decline go back to at least the 1950’s and arguably way before that. Trade union relations, under investment, wrong investment, insufficient infrastructure investment outside of the south east, incompetence, mismanagement, under investment in education, wrong focus and constant change in education policies and priorities are largely, but not exclusively, the root causes of that descent down the slippery slope and has very very little to do with DEI. But hey, don’t let me spoil your ignorance.
