I don't believe that's true. People today are better educated. For instance, compare maths/science exams to that of previous generations. In terms of general intelligence, I'd argue people today are far smarter too. Primarily due to the internet and the sheer wealth of information consumed over time at a fingertips notice. Curious to what makes you think otherwise though?
Appreciate you want to keep your traditions and that's fine but you must also understand why younger generations (and most non-UK people) think it's all a load of nonsense. From a logical point of view we're talking about an archaic institution living a lavish life by virtue of birth right and all off taxpayer money, in 2022. It's not about being woke or disrespectful - just seeing the situation for what it is in reality.
