well, in Toronto (not any cheaper than London these days) teachers easily make almost double what they do in the UK - about £49k, and there is plenty of opportunity to earn more in rewards and incentives (which, unlike in Britain, do not generally make the recipient worse off than they were before).
countries which take education seriously, and which routinely eat Britain alive in educational performance (according to the admittedly flawed metrics that measure these things) take teaching training very seriously, and pay accordingly - Canada, Finland, Singapore, Hong Kong etc. none of these are cheap countries to live either.
meanwhile, in London, nearly half of the people the government who the government has paid to become teachers have left in the past five years because the hours and stress are so high, for so little reward.
I really think you should set aside the instinctive contrarianism that swells in you any time I post anything, and think seriously about what the state of public services will be like if the current state of affairs continues.
and it is not just that i'm an incorrigilbe lefty pinko wannabe academic; even
@zzr45 has stated that the government needs to do something about housing prices, and he responds like a cat thrown into the bathtub if he so much as overhears somebody say the word "left".
you are always banging on about the importance of retraining people, but who exactly do you think is going to do this when we are not even prepared them to pay enough to support a family?
in an odd way, much like the Brexiters, I am not sure you understand the sort of intellectual competition this country is up against, and we are doing just about everything we can think of to make ourselves less competitive.
