I think Scotland deserves an honourable mention here. Bachelor’s degrees are free, under a scheme called “SAAS” (Might be home and EU only). Interestingly, people from England have to pay the same in Scotland as they do in England.
Alternatively, put much higher taxes on flights, and fund train/coach travel to make it more afforable, so more people can take lower impact, near home trips.
I’ve lived in north western Europe my entire life, and enjoy travelling by train/ferry and explore neighbouring countries - there is more than enough to see for a life time. It is astonishing to me how many people find it neccessary to fly to the other side of the globe to feel like they are on vacation (or more likely.. for vanity.)
