I do not believe Corbyn will be able to generate the billions he needs to fund his policies
Nor do I. For a start he's double counting a lot of extra taxes he thinks he's going to raise. He's also underestimating how hard it will be to target the illegal tax evaders - if it was so easy why didn't Brown do it over his 13 years in power?
But the biggie - he's planning to raise billions extra by making the global companies pay more tax rather than "offshoring" their profits. But he's missed the elephant in the room. The current government is already doing that - the UK is one of the early adopters of the new OECD global scheme to make companies pay taxes in the country where the profits are generated - it's already happening today! It's not "new" money anymore.
For offshore personal tax evasion, the UK has recently agreed with 90 other countries to share information about savings, bank accounts, etc., and those illegally evading UK tax by trying to hide money offshore are being caught and made to pay up - it's already happening now, today, yesterday, tomorrow. It's not "new" anymore either.
Corbyn isn't introducing anything new in these areas - so it's not new money that he'll be finding at all. It's just one big lie, based on how things used to work a few years ago. I just can't believe how gullible people are to fall for it. Corbyn has a huge black hole in his figures and that means he can't deliver on his promises and the deficit will shoot up!
