In the next two years we will be leaving the EU and embarking on a new global future for Britain. We have now seen how Labour intend to prepare for this economic adventure. They will put up corporation tax, increase taxes on those that own businesses, nationalise private industry and specifically target the financial sector misguided taxes.
The result of all this will be to cost jobs and deter investment. So at a time when we will need to be globally competitive Corbyn's solution is to deliberately torpedo our economy in some self deluded quest to return to the 1970s - a period that saw us described as the sick man of Europe.
What's truly disappointing is that he hasn't even done his sums properly. The estimate is that he would need to borrow at least £230bn to re-nationalise large swathes of our economy, which will of course cost money that he has, yes you guessed it, not budgeted for.
Don't worry though it gets even worse. He has committed to clearing the deficit within five years - that means finding £52bn of tax rises or savings that he hasn't spelled out either.
The true cherry on top of all this is in relation to the 50% tax rate. I know that it's always popular to try and 'knobble' the rich (lets just ignore that the top 5% already pay nearly 50% of all taxes) but in 2014 Labour were saying that the drop from 50 to 45% tax rate had cost the exchequer £100m - and yet in their manifesto it is apparently going to raise billions. Did they give the calculator to Diane Abbot?
It goes on - the Adam Smith Institute estimates that Labours massive tax raid on businesses might not raise a penny of the £20bn they hope it will but could actually cost the economy £8bn as investors look elsewhere.
Mr Corbyn's grand wish list may sound great, but if you can't raise the money then you can't pay for it. He may as well have promised us all a unicorn and a month of Christmases.
Yesterday proved that Mr Corbyn isn't just a security risk, he is an economic risk as well and I hope voters remember that on 8th June.
