Could be those who believe we can afford to improve state education, supply free free school meals to all, free music lessons and heaven knows how many musical instruments , scrapping tuition fees , proving good social care, saving the NHS, and much more have allowed rhensekves to be brain washed
Or they simply have seen the proof that it is possible, believe - unlike the politics of despair above - that is can and should be done. It is possible to keep following the sort of right-wing message of your post as the Conservatives have been doing or you can choose to have a more social-democratic state but it is a choice. Each one has it's cost but you chose which is the right cost to pay.
