There is no justification for voting for Farage, whether or not you wish to change or leave Europe.
On the hard left socialist agenda, with high public ownership, I truly wish it could be made to work. Real world experience indicates it has greater failings than the imperfect capitalist model. There is less accountability, as the controlling power (there has to be one) is over invested (literally) in not failing, and redundancies or death of a whole industry becomes acutely difficult, vis mining, however necessary. Aberfan was caused, in part, by a national coal board paralysed by its own implosion.
Also, to take this to a natural conclusion, Corbyn should be a leave advocate, as he could then borrow, subsidise and nationalise and increase working rights well beyond what EU rules would allow, the EU rules would hinder some of his ideas.
Honesty, he has some merit, he is too weak, too left, and about 50 years too late.
