Congratulations for posting something so incredibly negative, you risk derailing a very interesting thread. Perhaps you are not very well travelled, or are limited in outlook however at some point you may stumble across the real facts. Just for info.
I'm a well-educated and reasonably well travelled university graduate with a breadth of outlook that comes from wide reading, a mixed heritage, a diverse group of friends etc.
I'm highly aware of the funding pressures on state education, caused by Govenment spending cuts. Lots of teachers jobs have gone in the city where I live. Some schools are now closing at Friday lunchtimes.
Meanwhile the rise in unaccountable academies has often led to heads paying themselves - and families - a huge amount of money, while under-investing in the children
My background is also one where one of my parents came here as a refugee. There has been a rise in racist incidents in the last few years which is directly related to Brexit.
Language teaching is undegoing decline. School libraries are under-resourced. The curriculum is narrowing. There's a rise in relentless testing which makes some children feel like failures.
A lot of staff are leaving UK universities as a result of political uncertainty. UK's involvement in prestigious international research projects is also lessened and universities are already slipping in terms of international rankings
So while my daughter had a good state education and has recently graudated from an excellent UK university, the future isn't looking great at the moment for UK education generally. (I don't think a dash of extra-curricular Mandarin is going to solve this one.)
More broadly a lot of industries are starting to relocate. So I believe that by ensuring that whatever happens, my daughter can work in the EU27 countries, I've done something that may turn out to be extremely useful.
